Im scared to be truly happy because I think all the time that something bad will happen and destroy my happiness

Im scared that if I start to think it too much, I will start to believe it, and it becomes my reality. I always have thoughts like, “Do I love him, what if I lose feelings, how longs is this going to last, when will these thoughts finally go away, is he the one for me, is this how love feels like or am I just convincing myself?” I start to search things up to make myself feel better but the longest that works for is a few hours and then that gut wrenching feeling comes back. I love him I’m sure of it, but then why do I feel like this? I know if I didn’t love someone I would let them go and would t even fight for it or try to get better, but for him I’m trying ever second of everyday and sometimes I just feel so hopeless. I can’t afford a therapist and I’m too busy to talk to one. I don’t know what to do or how to feel, sometimes I just feel numb and I hate it, sometimes I feel like crying but can’t, and most the time I don’t feel jealous anymore and that scares me because I’m a jealous person. Then I get thoughts and reminders of my ex. Not in a way that I like them but the hatred and the trauma and pain they left me with. The mental, verbal and physical abuse. Sometimes my current relationship reminds me of him and why I shouldn’t be in one because I always fall into this deep hole that feels impossible to get out of. I just get so scared.

I usually would say I’ve never been depressed , but recently in my life since my anxiety/ocd has been so bad and having relationship problems I’m feeling kinda sad / stressed. I keep getting scared of being depressed I keep having intrusive thoughts of “ you’d would be better off if you weren’t living” “ I don’t wanna live if it’s like this” and it’s just scaring me 😞

I’m thinking about doing erp but my ocd is so severe the thought of accepting my fears happening to me makes me sick to my stomach. I also believe in the power of my words and saying I accept this Bad thing will attract it into my life. I’m not sure what I should do🥲
