Did something terrible during a manic episode. How do I handle the guilt?

I live in a house with several roommates. I had my first genuine episode of mania earlier this year. I was about to kill myself.

Turns out, one of my housemates used me to buy alcohol. I'm only just finding out about this. I am going to be in big trouble. I don't understand. I genuinely think I blacked out because I can't remember it. I don't know when it happened. I don't remember helping them buy alcholol. I might be facing homelessness because of it. It's challenging to me. How do I navigate this situation?

How do I deal with the embarrassment and shame?
