seeking for guidence

I am 14 live with father who is mentally ill and mother who is always sick but not really, yeah she has lupis and diabetties shes 300 pounds disbetties would go away if she lost weight, she loves being sick thats all she talks about, it gets her attention but I see threw it I watch her lie to get attention from family and friends or just to lie, we could be at the mall and if someone calls askes for a ride she will tell them she is sick and cant leave the house, I have been tested for lupis my A&A was high but I was never actualy diagnosed at all, but my mom insist to me and drs that I have Lupis and Dr gave me a bunch of medication I mean I fill up a 12inch by 12 inch with all my medication, I have told my mom that the medication makes me feel sick she wants me to take it anyways and is trying to get social security for me and her my dad already gets it for his condition. My mom told the dr that I am to sick to go to school so I have been on home school for almost 2 years now. I am missing out on so much I am a freshman, I sleep until noon everyday and so do my parents then I get up eat and go back to my room where I sit or lay all day, “NO I AM NT SICK” I stopped taking my medication except for the one for my autoamune system and feel much better, mom told the dr I was depressed so he gave me a antidepression medication. Iit wasn’t until I went to visit my aunt that I realized how good life can be, no one there is sick everyday, they dont lie to eachother, I wake up at 7am every day shower and start my day I never took my anti depression med the whold month or so I was there I never needed it. When I returned back home it star6ted all over again the drama, sitting in my room, the lies the drinking and acting out of my day the fighting. My asma never botherd me eather at my aunts she lives by the beach, but my area I cant breath. My aunt asked my parents to come move with her for my and there health the had to move out of the house we were in any way I begged them to move told them I was happier there and healthier there and the medical system is better there. They wont let me what can I do
