Feeling to check or do about something

i just installed this app so i dont really know what im doing, but if you see this please reply: do i have ocd? when i was younger, i believe i had ocd, due to me have to do things a certain number of times, for example when i got in a car i would have to tap the chair in front of me at least 4(or an even amount) times or else i was just feel..incomplete? i dont know the name for this feeling, but it is very stressful. there were many others things i had to do like this. then after awhile this symptom went away until this past 2 years, but it is much worse. i still do the thing where i have to do things a certain amount of times, but now i also am just really afraid of things being out of order, not necessarily messy, but in a place which i dont rmeber where it is, and i dont trust my self if i did something, for example shutting a door behind me, i have to look back like 3 times to make sure i actually did it even thought i definitely did, but i just have to make sure or else i have the feeling of being incomplete. sometimes i have to shut jt over and over again. i make sure i do these little things such as putting one coin in my pocket everyday and if i forget it so stressful to me to the point of tears and breakdowns. this stuff makes me extremly stressed and sometimes i have to go back to harming myself to relieve this feeling, which isnt good, but its like the only thing i can do to solve it. there are many more things that i do that i think is ocd but the paragraph already long so just please let me know if this is ocd?

Prior to coming to college, I knew that I was having thoughts that other people weren’t having and that it controlled my actions or feelings of guilt in a way that I just couldn’t see in my friends but I ignored it. Since coming to college, my compulsions and stressful thoughts have gotten a lot harder to handle and my new friends have started pointing out that they think I have OCD. I’ll try to explain some of the reasons people have pointed out or I’ve noticed but at the end of the day I always question if I’m just doing these things for some sort of attention or something. I have this strong belief that when I’m walking on pavement, the amount of times that I start stepping on a tile with either my right or left foot have to match. And people always ask me if I’m just superstitious about stepping on the cracks but I don’t mind that as long as I make it match with my other foot. The problem is that whenever I’m unable to “make the tiles or cracks match” I feel like I’ve left some universal channel open and something extremely bad will happen to me in the next 24 hours (after that it resets). Sometimes it makes me look weird when I’m walking and it’s really embarrassing when people ask me about it and I can’t fully explain the concept to them. People generally just get confused and I feel like they just regret asking and think I’m weird. Once, when I was walking down the street with some of my friends, i ran out of tiles to make my steps even and totally FREAKED OUT. I got really anxious and I couldn’t stop bouncing my leg. One of the people I was with made me feel terrible about it when he said “wait that’s actually real?” So now my fears of faking OCD just because has become a bit more real to me since my friends don’t understand the full extent of how it makes me feel, even when they’re actively seeing me break down. Besides this, which is really the most inconvenient part of my potential OCD, there’s a multitude of other things I’ve noticed that show signs of it. Whenever I take a test, I have to be wearing at least 2 hairbands on my wrist and be wearing a sweater in order to do well. Numbers really matter a lot to me because they each have a different meaning and I’m scared of some of them. When I was little, and even now in other instances besides sleeping, I used to count how many times I rolled over before I fell asleep in fear that I would land on one of the bad numbers. For example, 1 would mean a serial killer was in my room, 3 would mean something would come out of the mirror, 4 would mean a doll came to life and was trying to murder me with a knife, etc. They all sound like stupid fears and are highly improbable but it used to feel very real to me. Now I still associate those numbers with the bad things but I’ve worked on trying to expose myself to certain numbers some nights and find some safe ones. Now the number 4 has changed in meaning and evolved into my worst fear, the zombie apocalypse. This all ties back to my tile crack issue because when I “leave the channel open” by making my steps uneven, the number I mess up at (ex: 4 tiles started on the right means I need to start the next four with my left) is the chaos that the channel will bring. Also, I constantly feel like a terrible person because I’m scared that I’m faking my sexuality even though I only like girls. I’ve been closeted for so long throughout high school that sometimes I feel like my current shame and fear of telling important people in my life (ie. parents, family friends, people who I feel are slightly homophobic) is a sign that I’m not like devoted enough to my sexuality – making me scared of calling myself a lesbian. I’ve also never been with a girl because I only recently came out at college and it fuels my rumination that I subconsciously must just be asexual or once again doing it for attention. I’ve tried dating guys to make my mom believe I wasn’t lesbian but kissing them or the thought of spending the rest of my life with a man always makes me literally cry. I go to Virginia Tech and the lack of an LGBTQ+ community here is making my coming out process and search for a true relationship extremely difficult and bleak. Whenever I see a girl I don’t find attractive (even though I see a bunch that I do) it scares me and makes me think I might not actually be lesbian even though I like girls. Idk what to even say about this it just sucks. There’s so much more that I can relate to based on the discussion board such as fears of accidentally having pdophelia and cheating on people I’m not even dating. But at this point I feel like I’ve already written an essay and I don’t even know where to start with the different types of OCD and where to seek a diagnosis. The hardest part about asking for help or guidance is the fact that I never attempted to get diagnosed, making it feel like I can’t even claim that I have it. Thanks for reading this, please write back if you can relate at all :)

Hey, so I've never actually been diagnosed with OCD. I did a little bit of research, I always thought OCD was organizing things. But I'm not normal, I have this thing where I feel something isn't right. I obsess over it or if I brush my hand over something correctly then it's fixed. Or I have to do this thing on stairs, I'll walk up a few or down them because something isn't right. I read this thing on memories. I know something happened, but then I doubt myself to the point I don't know if it happened. And I think too logically in relationships. I'll put statistics on things and if they might not work out I distance myself, there's other odd things I do. My family always told me I was fine but then said things like I was messed up, and said to just ignore what I felt. Like I was making it up. I don't know what to do, I don't have a doctor currently, I was never diognosed. Is there a way to be sure I have it? Or a way to stop everything? I just want to stop everything, please and thank you. Sorry for the long post. If anyone can help, I would be so thankful.
