<human>: As context, We all live on college housing. My roommate hasn't been the most emotionally stable of people at his first time in college. He's been having relationship problems, skipped a lot of classes, had troubles with my two housemates, etc.

About a week ago I bought a new electric razor, and about a week ago I saw blood stains on his bed sheets. I didn't think to connect the two. Just today I caught him using my razor without my permission. They were his hairs on it, but after seeing him walk out with could've been atleast twenty cuts on his arms I decided to investigate the sink. Honestly, its a dirty sink but I did think I saw a blood stained toilet paper.

Can you provide a brief rundown of the text in within 3 sentences?
<bot>: Roommate used my razor without permission, saw a lot of somewhat fresh cut marks on his arms. I believe he's been using my razor for it.
