Hello ((KAIKA))). I am sorry for your struggles at this time. The main thing to remember at this time is to keep yourself safe at this time as well. Your brother is going to have to live his own life and make his own mistakes, and you ned to keep your mental health safe and try not to become the mediator for the situation for your own sake.(Easier said than done I know). Please think about yourself at this time and less about the situation that is going on in the household. Take care and PM aytime if you wish. Soidhonia
