Why are people trying to control me and spread gossip about me?

There could be lots of reason.
Bullying is nasty and it generally stops when you stand up for yourself. I’m not suggesting that you are to blame in anyway at all. Is it possible for you to confront these people?
Have you told your family? They are best placed to support you especially if you’re wanting an arranged marriage
Bullies are usually insecure and unsuccessful.
You will find a wife who will see all your good qualities and what a great man you are. And you’ll work hard and hopefully build a successful business too. The best revenge will be your success but in the meantime, try to get some support from your family and friends. I’m sure it’s hard but do things that will build your confidence and self esteem and give them the finger!!!!
In the meantime, you can pm me anytime you’re struggling if you want someone to talk to
Very best of luck

Thank you very much for your reply.

Unfortunately I've been picked on, insulted by some of my uncle, aunt's.

And my uncle and aunt's do nothing, they could easily give them a word or even stop it but they don't.

The only reason this is happening is because they know they will easily get away they do it time and time again but my uncle and aunt's don't do nothing.
