I feel like love isn't possible for me

Hi guys.So a little about me, and why I don't feel like love / a relationship is possible for me. Any advice would be great <3So I am in my early thirties, overweight due a medical condition, I live in VERY small town in the bible belt where I take care of my elderly mother. That's just what I feel like is the start of my issue lol.I have a very particular type - not meaning just I am only attracted to certain types of guys - I mean in the most hardcore of ways I am unable to enjoy sex with, or develop anything beyond a friendship with anyone that doesn't fit into that type. It's something I even went to counseling over in the past, and not something I have overcome, I guess you can say I am hardwired that way.There are no lgbt friendly places in my area to meet people, and I am unable to travel very far for long due to the poor health of my mother. So considering all of that, I don't feel like I have hope for the future.I have tried dating apps such as Grindr, MeetMe, Tinder, Match, etc, and no surprise to me the folks I am generally attracted to are not in the market for a "bigger guy". Over the years I have had two relationships that turned out the scumbags were just using me for money, or a place to live, but at the time I am ashamed to say I was desperate enough to take what affection I could get, regardless of why I was getting it.I want to find a partner, and maybe one day have a family - I feel like I have so much to offer someone. I like to think I am smart, funny, social, informed, with a kind heart, and I can pretty much find enjoyment in any activity. I am just stuck in all of the above mentioned things.Should I just settle down with someone I am not attracted to that will have me? Basically take what I can get, and stop hoping for that right person to come along one day? I mean I guess there can be a certain kind of happiness there, at least I wouldn't be alone, but would that be fair to the other person - I've tried it before, and everything about it just felt fake and I don't like being that kind of person.Has anyone else ever experienced something like this? Did you find your Knight in shining armor? Does anyone have advice on how I can find someone considering my circumstances?I'm sorry for the wall of text, and what is likely fragmented thoughts. I just don't know what to do anymore.
