My grandfather suffered from BPD. My mother and I both swing hard enough to where I think there might be some imbalance, but we have both been able to remain mostly in touch with reality. 

However, my (22) brother (18) is starting to worry me. He was been getting into music, which is great especially considering it is a hobby of mine. But recently his hard drive crashed and he hasn’t had much to do. I left for school about a week ago and took his hard drive with me to get his projects off of there and reinstall a fresh copy of Windows. 

Anyways, he had been working as a delivery driver until a few days ago when he up and quit his job out of nowhere. He only slept a few hours the night before, and instead of going to work he just went to the gym and stayed there for like 8 hours working out. My mom told me all of this, and when I called him I could hear he was still at the gym. He got mad that I asked why he quit, said he didn’t want to work for a company anymore. That he wanted to pursue his dreams of becoming a personal trainer and a rapper and that I shouldn’t get in the way of that like mom and dad. 

The day after he broke down to my parents. Said he was being self destructive and was going to stop smoking weed (which he has really dove into). That he needed to go to counseling. But then the day after when my mom tried to make the apt, he said that he didn’t need that, that he had found God, that he felt great and nothing was wrong with him. He has been walking around the house naked?

None of us know what to do. We have no experience dealing with someone like this. But I do know that he is pretty volatile right now and that it’s best to not villainize ourselves in his eyes. My phone is starting to die. Any advice is appreciated. Thank you.
