Struggling with Socializing and Chronic Pain: Need Support

I have such a hard time meeting new people and making friends because I am an introvert. It also doesn't help that I deal with chronic pain and other medical problems. I have been knocked down by people I thought cared but turned out they could only see me for my disabilities, not the real me. The lack of a good strong support network makes it super difficult to stay positive and not get depressed thinking no one will want to become my friend. I shouldn't even care about this but I do because it gets very lonely. I spend most of my days at home due to driving restrictions and I can only limit myself to small stores and small tasks. If I go anywhere that requires too much walking I have to use a wheelchair due to breathing issues and leg problems that consist of pain, heaviness, weakness to the point where I can barely walk. People that knew me prior to these new conditions think I am being dramatic about it but I am tough as nails so not sure what gives them that impression. When I mean tough I mean that I can handle a ton of physical and mental pain before cracking. For the most part I have everything under control to the best extent possible but at least once a week I get down from lack of human interaction or some sort of connection. I do have a partner but they work a lot since I can't anymore. Also my partner has been supporting me for the last two years as I fought through my disability denials and trial...finally got it approved. I just wish I knew a way to connect with others in person or even a texting buddy...I am not good about keeping up on this app as I get easily overwhelmed. I haven't been tested but I am pretty sure I either have high functioning autism or something that shares the similar symptoms. I guess I have blabbed enough. Praying that eventually I can have friends that actually care to be part of my life. My own brother, father, aunt etc don't even talk to me! Ok done
