Nothing bad about that. I have been admitted more times than I can count...I just know it's in the higher double digits. Never feel bad for seeking/getting help.
As far as the dorky roommate...any staff would know you can't die from swallowing toothpaste..sounds like she was having issues that had nothing to do with you.
If you ever get admitted again, you got to remember when the other patients start stuff, it's usually something going within themselves and better to just ignore it.
