My friend has bipolar disorder and struggles severe depression/anxiety. He takes a fuck ton of pills for this stuff, and recently he checked himself into the hospital.

This is a friend that I can see having for a long time. I am scared guys, I don't want him to go away or get sent to a ward. If he does get out, how do I deal with his anxiety and depression issues? We will be rooming together next year and he does things like crashing my place at 5pm and not waking up until 5pm the next day because the pills hit so hard.

I hope the hospital fixes him up. Anyone with depression/anxiety have any advice. How can I be a good friend? I have never had a best friend in my life, and I was so happy that he could be a best friend.
