I got bully from my family for being fat

I don’t know if this happen to you guys my people would always ask me whats my weight why being so fat like a pig or like a buffalo and that world hits me for my entire life I don’t understand why they are so serious about body type even I’m fat or thin I’m still be myself why would they encourage me to be like what they want i just want to the way i am. People would ask me if I’m 100kg now or what Thats my Trauma I don’t wanna keep going through this. I know they care but I just wanna be like this I’m happy in what i am, I just don’t want to change myself to anyone even my mom didnt even understand me.
