I’m scared my good karma is going to bad

I am really worried because I felt confident about my appearance today, then I found myself thrown into imagining if I did certain things like flipping my hair or just looking good around a certain coworker and they'd find it attractive. I don't like that coworker at all and I'm in a happy relationship with my boyfriend, this made me feel awful and I starting feeling disloyal again. I don't know if it's an old habit, a desire for external validation, or what. I can't tell if this was a thought pattern connected to my last post or not. All I know is that I'm really stuck right now. I feel like every time I pick myself back up, I fall right back down again, like there's ice in the road. I can't help but feel like everything I touch or everything I think about crumbles. I feel like my own mind is against me and I don't know who to trust anymore. These small OCD spirals are really messing with my work life, s*x life, everything really, and it's getting to me. I feel with every spiral that I'm getting sucked into a depression again and I don't know what's next. It doesn't matter how small the "bad" thing that "i did" was, but I feel that every little thing is building up to a point and something is going to crash down. I need help. What do I do? Right when everything around me seems to be going up, I feel like I'm being dragged down and I can't do this anymore. Please help me.

I just got broken up with 13 days ago after 5 months super unexpectedly for no reason other then he needs to work on himself. That night i was really alone because my parents told me he was a good influence on me and my friends weren’t so i had no one. I added this guy on Snapchat that same night and we’ve texted and called every night since. We met 3 days ago and it went really good. We were both nervous but both talked about the next one and how we both had fun. Last night he went to bed without even a goodnight or any talking that whole day but apologized and said goodmorning this morning. Then tonight he randomly sends a paragraph saying he doesn’t think it’s going to work. When i asked why he said “Idk our personalities are just a bit different and idk if I’m really ready to be in a relationship”. It makes sense i guess but I’m really struggling with the fact that my last relationship said that exact same thing and i can’t help but think there has to be something wrong with me. I never cheated or did anything that could’ve upset either of them. I’m 17 and i really feel like i should just stop trying for a relationship but no one is giving me any kind of advice so I’ve just been over thinking all of it. Any past relationship I’ve gotten over by meeting someone new but I don’t know how to “work on myself”. I really think I have a fear of being alone. Please help!

I apologize I post here a lot lol. I have a few questions/I want to vent about this. My therapist and I have identified one of the triggers I’ve been trying to work on, which is my fear of never being good enough; for myself, my family, my friends, for my romantic relationships, and just in general. Honestly, I hate myself so much. Not for any reason in particular, but I overanalyze everything I do and let it consume me. I know this is normal for most people, and everyone goes through bouts of self depreciation and lack of self love. I’m trying to give my love to myself that I’ve always given to other people and it’s so difficult. It’s really funny, I need male validation even though I feel like I can never trust a man ever again. I was broken up with at the beginning of April, and so you can imagine how my self worth really has been feeling. I’m aware my self worth isn’t based on other people’s perception of me, but I just want to be loved consistently through my ocd and adhd. It feels like it’s too much for people, while I simultaneously feel like I’m making this a massive deal. I don’t want to get into another relationship ever again, I just think I’m too weird for most men or they’ll take advantage of me for something again. I think if a man is nice to me, it means there’s an ulterior motive or a catch. There’s genuinely no way someone even cares as much about me as I do them, it’s always one sided. I love my friends, I’m taking about relationships wise. Not to mention, I hate the way I look and act. When I think I’m somewhat decent looking, there’s always a post to pop up with this stunningly beautiful girl. I can never catch up with modern beauty standards. I hate this so so so much. I hate feeling this way, how do I make this all stop?
