Neediness & OCD & uncertainty intolerance & relationships

Hello all! I'm a 25 years old male. Let me give you a quick summary of my past and then I'll talk about today.

I was diagnosed with OCD when I was 12 or 13. I was afraid of going to hell and in order to deal with this uncertainty I asked people lots of questions, looked up religions that can give me the guarantee that I'll go to heaven or at least I'll be ok that nothing bad is gonna happen when I die. I kind of got rid of this when I was 19 by listening to logical arguments by some skeptics.

Now, my biggest problem is the fact that I'm scared of not finding love again. I met with a woman when I was 21 and she was 31. It lasted for 1,5 years. After that I tried finding a girlfriend but couldn't manage it somehow. I'm 25 now and incredibly needy. There're "what if" thoughts on my mind all the time. "What if she doesn't reply to my text? What if we go on a date but then she doesn't want to see me again? What if she misunderstands me kissing her on the cheek?" etc. And probably because of these thoughts I've scared women that I've met away. I kept texting them to get guarantee that if we're gonna certainly meet or to understand that if they're still interested, etc.

I just need a guarantee that I'm gonna find a girlfriend. I know that life doesn't give guarantees but I just can't live that way. I also need to know that I'm not cursed or I don't have unluck in my life. I'm scared of being alone forever or finding someone only when I got old.

I'm seeing a psychiatrist now. Before him, I've seen many different psychiatrists and psychologists, used lots of meds; none of them worked properly. And some people say that the meds don't cure, they only help you with the symptoms. And that's very discouraging.

Doctors say that I still have OCD. In fact it's a resistant OCD. I also have an intolerance to uncertainty. I'm also very needy. When women don't reply to my text, I get highly anxious, those "what if" thoughts start coming into my mind and they leave me paralyzed with fear and anxiety.

I have no idea what to do.

Any advice? Thanks.
