Gay, Disabled, Dating Shouldn't Be This Tough

Hello, First time here on Reddit, and thought maybe a different venue might help me gain some perspective on my issue. I am disabled, and I am gay and wonder if it's even worth trying to find anyone at this stage of my life. I'm 38 and have had only two relationships-both quite short. I have a rare bone disease coupled with a kidney transplant. For the past two years I have been seeking out someone to date, or even form a relationship with. I had been talking to a guy who said he didn't mind the wheelchair and then told me the wheelchair is an issue (yet he ended up in a relationship with someone in a chair-go figure). Maybe it's my looks, maybe it's my personality, not sure. I have seen other posters who mention how they feel looked over. That is exactly how I feel. I have always kind of been shy when it comes to meeting others (though the shyness quickly melts away once I get talking). This shyness goes way back to when I was a kid even. When I went to Pride this year, I certainly was ignored, and when I wasn't ignored people were pushing my chair (it's a sports chair so it's more like they were pushing my shoulders), rubbing my head - and one even rested his beer ON my head. Do people actually believe there is someone for everyone? Should it really be this hard to find someone? I mean, it's a wheelchair, nothing more. Any thoughts would be appreciated, or really any help even. Thanks, everyone.
