bullying (?)

Hi...so, idk if it's the right place because Idk if this thing I'm living is bullying...well, I always try to be unobserved and "in my place" because I don't like spend time with people I don't like (I spend time only with my family and my few friends). However, in the small town where I live a lot of guys kid me because of my shyness and my weight (I'm enough curvy, especially for my bottom). Is there anything to do to don't be sad and depressed more than now? I accept every kind of advice.
