I feel like I was wrong last night, like I should have said something to the people being noisy and annoying and stuff...

Noisy people are a touchy situation, especially when it is such the norm. I don't think that it is so much your problem to solve as it is the people who are in charge of the place where you are living. Here, we wouldn't handle it ourselves because it would be messy. Here we would let the authorities handle it.

I'm in so much pain after eating yesterday and it's my stupid fault for eating yesterday. I shouldn't have let Charlene force me like that. I was weak AGAIN.

What is wrong with this paragragh? ^........... You are taking normal body functions that are vital for survival and you are twisting them and making them false.............

Are you punishing yourself because you think that you didn't handle last night correctly?
