I really really need your help right now.
I've been suffering from anxiety for years... I was obsessed with having some kind of phisical diesase, but noone took me seriously. Long story short, after months, years of suffering, even thinking of giving up, i think i finnaly have that under control, i can deal with that issue by now.
Six months ago i started dating a girl, who's been my classmate for 8 years. I was incredibly happy for a little while, but then i started feeling strange. I didn't want to be with her so much, i wasn't sure if i loved her (as of feeling it), but in my mind, i know i do/did. A few weeks ago it got much, much worse. Now, whenever i'm not with her, i feel really really bad, whenever i think of her i get a lousy feeling, and i started noticing (at least my mind tries to tell me) that she's not that into me anymore. While usually, i feel like i have to break up with her, i can't imagine my life without her. Whenever i feel like she might break up with me, i get scared, and i just can't take it much longer. One minute i think i have to break up with her, even though i cannot imagine not being with her, cause she's absolutely amazing, and i have zero reasons not to love her, she's everythink i'm looking for, the other minute i'm scared she's pulling away from me, and is about to break up with me, or at least she's not happy, and thinks this isn't gonna work. This may sound stupid, but we were talking about starting our lifes togerher, always said stuff like: "This is not how we're gonna raise our child" and stuff like that, i was even planning to propose to her.
I was thinking about possible reasons why i feel the way i do. I never talk about myself, not even to her. She says a lot, that i'm very misteryous, she doesn't know nearly as much about me, as i do about her, but i always try to talk when she asks, only i'm not very good at it.
The other one i thought of, is that she introduced me to her parents months ago, they seem to love me, i love them. On the other hand, i didn't introduce her to my parents yet, even though she's really looking forward to it. Maybe i'm obsessed with the thought, that i'm not making her happy, i'm a bad boyfriend.
I would really need your advice, i've read about this thing called Relationship OCD, and it looks like a match with my current situation, although i was never diagnosed with OCD, it seems like i have a lot of psychological problems. Ending the relationship would kill me, i want the good feeling back, the one i only feel really barely now. I know she loves me, i know i love her even if these thought make me feel i don't. What should i do?
