advice please?

I’m not too sure where to begin so some stuff may be a bit scattered. I’d like to start with the fact that I’m not sure if I just have anxiety or if it is actually OCD. I’ve been dealing with these intrusive thoughts for as long as I can remember. TRIGGER WARNING NEXT PARAGRAPH Stuff like “what if my teacher just raped me in the middle of class” or “what if I pulled all my veins at.” Those are some of the more graphic and violent things but I do get lesser things like “what if I imagined that whole conversation” when I know for a fact I did experience that exact memory/conversation. I don’t like these thoughts and I don’t ever want to think them. If anyone has any advice it would be greatly appreciated. I’m only 16 and I want to be sure about this stuff before I ask my parents to get me diagnosed.

Hello everyone I need some advice. I’ve struggled with what I think and hope is ocd for a long time. It started when I was 14 I had a concussion and my brain convinced myself for 9 months that I had this concussion. Then I had a gf at 15 before we were official I did a terrible thing im regretful of it for sure. I kissed another girl. I told my now ex girlfriend about it and I started to overthink the situation and think maybe I slept with the girl or maybe we did more than kiss. In reality we didn’t. when I turned 16 I started having thoughts of maybe I cheated on her with other girls at our school. It would be false memories of me sleeping or doing things with 4 or 5 other girls. That eventually went away as I would ask reassurance like a crazy person. Then one day what I believe was either Christmas time or new years around that time I had this thought “what if I SA’d my ex little sister?” This thought tormented me for so long I couldn’t believe it. As she was so young it would be impossible for me to do that without someone noticing plus that’s absolutely horrifying and disgusting and I’ve never ever ever ever been alone with her or desired to. Then what I knew would happen came along with me thinking I SA’d my little sister or my baby brother at the time. It was a horrible experience. Then it went to me thinking I was a pedo without the false memories. Then it went to my other siblings thinking I did something to them in their sleep, I did something to the pets, etc. As I got older I realized what ocd was and what I was going through and it eventually all went away. But as time goes on I’m now almost 24 I have spiraled back into thinking I SA my ex little sister. It’s crazy because I’ve never had that desire or anything at all it would absolutely break me if that was true. With something like this saying maybe not maybe it did is crazy because it’s a serious thing. I’m getting therapy on Monday and am just wanting my life back. I just recently got engaged to my beautiful fiancé and I want to be regular again. Anyone have any advice or even have gone through the same scenarios? It’s just so tough.

I am 16 and struggling with OCD. It is causing me to do irrational things that I wouldn't normally do and cause issues with my parents. I feel like a terrible person and want to take back things that have happen and don't know how to make it better. The OCD causes things to get stuck in my brain and my questions have to be answered and talked about. I don't know how to let thoughts go and ways that would be healthy for myself and my parent when this happens. Any advice?
