My Relatives always insults me

Me 24(F) have severe chronic insomnia.If I sleep today I can't sleep for next 2 days. Because of that I'm always tired. I can't go to a job. When my relatives come home the first thing they do is insulting me. Saying I'm always lazy . I don't have anything serious. I'm just pretending. Seriously? Every day I'm struggling. Even my family is not believing me.Dr did some tests and found I have magnesium deficiency.i took magnesium supplements , I did excercise, followed a sleep routine.i did everything still no difference. My face is so bloated, I gained weight.Im getting uglier now People started mock me. Above that my relatives mocking me And laughing at my situation. I'm tired of this life
