My parents are acting Crazy what should i do?

listen, make the most of the time u have now. stay in school, finish with good grades cuz that can only help u in the real world. get a part time job and put money in the bank so that when u have reached ur imit nothing, especially money, will get in ur way. you only have 2 yrs to get thru, they will go by fast. during that same time teach ur brother the same thing u r learning now so he can protect himself too. good luck to u
