A: First of all, I’m sorry that your brother was so mean to you while growing up. As common as this can be, it is still wrong and can leave lasting scars. I’m also sorry that your parents didn’t do more to protect you, but hopefully they will this time around. I would let them know how scared you are now, before he even moves back. You might even consider showing them your letter and my response. Sibling abuse is real. Here is a link you might find helpful: http://sasian.org/.
You did not mention how long he has been out of the home, but I can only assume that you have both grown up some since the abuse occurred. You will be better able to defend yourself if need be and to avoid being near him if he starts his old behaviors. But, hopefully he will have matured enough that he won’t treat you the same way as he did in the past. If he does, first, tell your parents immediately, and secondly call the police if he physically harms you. You have a right to feel safe in your own home.
All the best,
