<human>: Can you condense the text into a few key points?

Okay. So I'm trying not to be a psychotic roommate, but it's testing me right now. When I got back from my business trip earlier today there were these weird stains on my sheets so I asked my roommate if maintenance had been in my room. She was like oh, I'm so sorry, I blacked out on Wednesday and I think I might have crashed in here. So she washed my sheets. AND I WAS LIKE 'ARE YOU FUCKING KIDDING ME' in my head. But out loud, I was like it's okay I understand shit happens, I'm just glad you made it home okay.

But.

I just got up to go to bathroom and when I went to open the seat, there were 2 packs of tissues in the toilet. I get them out, pee, flush, and the water starts to rise. So she fucking clogged my toilet.

I want to be understanding, but honestly this is the last thing I want to come home from after a fucking week long business trip. I feel like at this point because there are 2 somewhat large things, I need to address the fact that this is unacceptable.
<bot>: How do I approach my roommate without being rude/mean/demeaning, but making sure I get my point across that I'm not happy?
