Mentally Ill family, long post sorry in advance

I nobody to confide in as of right now regarding my family so I think I will share you guys and hope that you guys won’t be too harsh/mean towards me.

Myself: I have been given the diagnosis of Bipolar mania. I take my meds on a regular basis, collect social security so that I may live and pay my bills, go to high school as a full time student in the AM, make my own lunches, on occasions get into it with my mother, stepfather, and stepbrother. I am also a Capricorn.

Mother: Has bipolar mania/depression. Takes her meds ( I hope on a regular) because she receives her meds in the mail, has been getting into arguments with me by putting me down for still trying to get my high school diploma, reading old books, and saying that I am insinuating that other people are eating massive amounts of food out of the fridge. She is a retired nurse. My mother is a Sagittarius.

Stepfather: Has ADHD, OCD and is currently on no meds. He couldn’t do his college homework with getting massive amounts of help from his current wife, he was just recently reprimanded by his boss for not taking the higher paying job with even more responsibilities and was told he only looks at the money factor. He sleeps no more than 4 hours every night and still refuses to wear his hearing aids because they are ugly. He is currently having his wife do his job resume because he has dyslexia and according to his wife and boss he does not know how to a proper resume. He is also not collecting rent money from his son.

Stepbrother: Is addicted to illicit drugs ( Shrooms, a bong), he is also doing marijuana which is now legal in the state of California. He skips school, has his father wake home up to go to work ( for which he only goes 50% of the time for) , eats my lunch food, eats out a great deal of the time and is currently eating other people’s food and cant recall whether or not he did so when people have caught him in the act. He’s up all night as if it were daytime hours disturbing me. Takes three showers a day, and gets into arguments with his father and stepmother. I try my best to avoid him.

What advice, if any, can you give. Please be sincere and not rude. Thanks in advance.
