It's not your fault, most people I think would do it were it free.
People with things that would seem
far more inhibitive end up dating just fine - I'm a chronic worrier and I know what it can be like to be in a mindset of worrying about something like that, but if you're just you - believe me, you'll find someone.
Also - I'm in like no good position to say this 'cause I'm not doing well myself, but something's telling me to recommend you "The Power of Now" by Eckhart Tolle. Good book - I actually haven't read all of it, but I've seen tons of videos of him on youtube, and everything with him is about presence, accepting the now and such (I think the book name sounds a little too self-helpey, myself, it's good stuff). I dunno - I get this feeling it's something you should check out if it sounds like it could be helpful. If not, well, figured I'd throw it out. Should probably take my own advice.
Best of luck - remember - all of us here support you, so you aren't alone - and you'll find someone when you least expect it (it almost always works that way for some reason).
Obstacles in life seem to be pathways to wisdom once we crawl our way through the pain and frustration, no? Just one step at a time, one breath at a time
