Hi foto, It is hard to see someone you love suffer with depression and refuse all help. It is even worse when they become angry and negative as this seems to increase your worry. My brother is like this also but he has BP and explosive personality disorder. You have to find someway to resolve with yourself that you are doing all you can for him. His decisions and actions are not your responsibility or cross to bear. You can not to take on his problems or his depression upon yourself. It is okay to be worried, concerned and involved and give him support and encouragement to seek help. Perhaps if this situation is effecting you to this extent you could talk to counselor or therapist about
it and they can give you some suggestions on how better to handle this situation. Take care ~ Elisha
