How can I make friends when people are discriminating against me for being short?

Im only 4ft5, I was able to make friends when i was younger but now that im 62, noone wants to make friends with me, not even in church, i live in an apt building and my neighbors never knock on my door to visit but they knock on everyone elses door, i rarely get phone calls from people, when i go to church noone ever asks me if i want to go out to eat with them after church, i wouldve gladly paid for them if they had,even on my birthday and holidays i get stuck by myself, not even my family wants to contact me, not sure why, i lost an identical twin 2 1/2 yrs ago, my brothers wouldnt even go to the funeral thanks to covid, i saw it on zoom but it wasnt the same, my parents have been gone for yrs, i couldve used that time to spend with my brothers, im not working now so i dont really get to see people there, i do live by a senior center and go there for lunch, i see people there and eat lunch with them but they rarely invite me to do anything with them, do people see me as a child cause of my size or do they think i have down syndrome, i heard some people with down syndrome are short, i thought of getting involved with little people of america but dont know if they have any in my area, ive also thought of moving to another apt building so i can make friends instead of always being with people not interested, any suggestions on how to get people to look at me like im their age instead of a little kid. my parents never showed us how to use lipstick and make up so ive never been into that, any suggestions, tired of being by myself all the time, guys have never asked me out on dates so i never got married and had kids, why are people so hateful towards short people? any ideas? tired of it.
