<human>: Can you give me a shortened version of the text?

I'm somewhat new to this so forgive me if I screw this up. M

y little brother is 19 and still lives at home. He dropped out of his first semester of college and stays up all night, and only gets up to go to his part time job for 3 hours. He has been hung up on his ex since they broke up a year ago which is why he claims he doesn't sleep. He has admitted that he thinks he is bipolar, but he is so "straightedge" that he refuses to take any medication. He wont even take tylenol or nyquil. He will have ups and down and I have tried explaining that meds are not always bad. (I'm on an antidepressant)  but he will not go. I have tried to talk him into therapy, but he wont go.This has caused many fights between my mom and I because I feel she is enabling him to keep his current behaviors. He gets violent and even smashes his head against the wall, there are currently 4 holes in the wall from this. I have tried talking to him so many times but it just goes in one ear and out the other.
<bot>: little brother (19) is most likely bipolar. He is "straightedge"  to the point where he won't get help. What do I do?
