How long should a person put up with ridicule from an elder and y?

I've been ridiculed since childhood by this elder. Others tell me it's jealousy because my life is easier than his...thanks to my parents. Yes, my parents came to the US, then once well settled, started a family. Only after that, did dad get citizenship and was able to bring his side over. By then, this elder of mine was married and had a family. But $ was sent home, and he was in the military and was a farmer too, so he wasn't dirt poor, just poor compared to one working in the states. He and his family finally got here about eighteen years ago. He and his wife didn't get good jobs, but the kids are well-educated and married well. They're well settled. I'm not. I have disabilities, but look and talk totally fine. I get govt aid. I have applied for and lost several jobs. This is primarily due to my slow movements and actions. Due to the way I talk and articulate things, people think I'm lazy. They just want to assume I'm faster some days and slower on others on purpose. I could go on and on about my issues, but the issue here is the ridicule. Ok, my parents are educated, my uncle and aunt are not. BUT, to me, that doesn't make them dumb. Actually, they're smart...except they use it to be cunning, instead of getting an education and moving up...instead of seizing the opportunity the US provides. Instead, they choose to ridicule me...a girl who's had all these opportunities, but couldn't accomplish anything. My parents let it slide...citing that that's how they've always been, and that it wont change. But now, I'm scared that when they get me alone, the ridicule will start...and if I don't go to their home, when they want me to, they blame my mom....saying it's because she said so. But in college I lived where they did and would visit. They'd give me food and tell everyone that they know american girls don't cook, and I don't know how, so they gave me food. This is a total lie. Plus, I would visit at tea time. Oh, they didn't like giving me rides to and from the airport either. They'd tell my folks, and I wouldn't mind it, because they're gossips anyway. But a while back...in india when we saw each other...w/o any prompting from me or anyone...my uncle states I cant come to his city, because if I do, there wont be any room in his home for me. He said he said this because his daughter and her family r always there. That house has four bedrooms. At most, only three would b occupied(Idk if the kids would sleep separate..they're small, but I said 3 rooms just in case). That leaves one empty room. He knows this. So I'm guessing he didn't want me there. So when I did visit his town, I didn't let him know. He found out, and invited me over for dinner. I didn't go...due to the earlier comment. The aunt I was staying with tried her hardest to convince me to go, but I took a stand. Honestly, I would've been a horrible guest if I went, and yes, THAT would be my fault...so I didn't go. I heard nothing of it since...but that was blamed on my mom too...though it was MY decision and both folks just stood by me.

I just want to know if and when the ridicule will stop. Because I really don't know what I've done to them to deserve such hatred. My dad told me to just take it as me giving them one wound for them giving me many throughout my life. If I ever do visit that town again, I only plan to go when invited, for dinner, but probably wont eat. I only say this, because his son-in-law was in my town when I was in his, and the son-in-law, DID come by my home.....so, only for that, I owe it to them to make an appearance. i tried to make this as short as possible, sorry.
