Welcome! Glad you could post...there seems to be a lot of heavy turmoil going on in your life. I hope it felt good to release some of that tension by posting.

There are many things in your post that cause me concern. I think the most significant one is the physical abuse you talk about from your brother and mom. It sounds like there is a lot of severe tension going on, also. Is there a relative that is not so closely linked to all this that you could stay with for awhile?
