After taking o e bite of food I'm full could this be related to hating my body

Why is it when I go to eat dinner alot of the time I feel full after 1 or 2 bites. Even if I haven't eaten all day. This also happens when I do eat all 3 meals. Is this normal??? I have to force my self to eat the rest of the meal cuz I know my mum won't let me eat that little.

Could it be coused from me hating my body. Cuz I did try starving my self for 2 day and it dident bother me at all. The only reason I stoped is cuz I read it slows your matabalizim down. But I started feeling full after one bite befor I stoped eating for 2 days

And I don't know why but I don't feel hunger at all. Even if I don't eat all day I don't feel hungry. I only feel When I'm full. But most of the time I don't feel anything.

Is this normal or should I get it checked???
