Don't get down on yourself, I'm bipolar and some times I feel like I would be a curse to anyone I get close too. You deserve to be happy too! Evberyone has ups and downs. Sure you can be a handful, I once dated a bipolar girl, she got crazier then me, like any relationship, yes we had a relationship, there were ups and downs. I broke it off, I felt the need to move on, we all get that feeling too.
Try not to think in terms of black and white, it's not so clear cut and we are in no worse or better position when it comes to dating or relationships. There are plenty of "normal" people that I simply don't like and would NOT want to be around them. Just get out there and get your feet wet.
Justugh, I'd quit while your ahead or still have a head lol, your swimming in dangers waters there buddy
