My brother is about 25 and has BPD. He lives with my dad in another state and has a terrible habit of getting a job, and self destructing and quitting/probably getting fired due to staying home (along with wanting to change career paths every several weeks, from wanting to own a pool business, wanting to run a land scape crew, wanting to then quit and have his own company etc..)

My brother used to live with my mother and I, and would also stay home from work (my mom didn't set boundaries or enforce him to pay rent, and he would throw stuff at the wall, scream, threaten to commit himsef etc)

Long story short, my brother is pretty much every day threatening to commit himself, kill himself, and come back down to live here near me saying that hes miserable by my dad. Saying he has no friends where he is (his friends are all near me), and that he can never be happy there..

Although I know happiness isn't a place, I do also know it is hard to even make changes when your bad behavior is enabled.

 I obviously feel bad for my dad for having to deal with this, even though my dad wanted him there to help him. I am 19, yet act completely different than my parents and I am a lot "harder". My brother respects me a lot, and I am not an enabling person. I have my own 1 bedroom paid for by my dad (child support $) and I pay all my own bills. My brother wants to come live with me, and part of me feels like I can't say no because My dad pays for this place, but also another part of me knows i have one bedroom and will be kinda stuck with him on my couch..

I have this gut feeling though that I can truly help him if he commits to therapy and meds again because I would come up with a plan and have consequences for his actions (I want to make a plan for work or something and chores he will follow before he comes down).

I will truly throw him and his stuff out of my house if he does not commit to the plan, because I refuse to be miserable or enable his behavior. I also know I am not the parent, rather his little sister, and this is not my responsibility to take care of hm and I shouldn't let him come stay with me (according to my therapist)

I am feeling very lost on what to do.  This whole post is a mess I am sure, sorry. Can anyone offer advice, or help come up with a plan I can make for my brother if he does move down?
