Am I an Asshole?

This shit has been such a rollercoaster of emotion. I just can't give a fuck anymore. No one that I know really understands what it's like to have a family member as fucked up as mine. I know it's a goddamn pitty party (Alex) but guess what you went to fucking bed. Not only that, but you've had enough of hearing about how my brother shits on me. If my brother is really mentally ill, than am I a fucking asshole for signing him off?
How can I continue on?
My mother is now going to meetings for parents of mentally ill. Am I an asshole?
