I've known this girl and her family for about 2, 3 years now. I was in a very dark place mentally when we first met, so I was glad to have made a new friend. When I went to her residence the first time, a trailer, I was shocked. I don't consider myself a neat freak AT ALL, but this place was in absolute filth. I guess a way to describe it would be... Hoarders (the TV show) Lite. A few months after we met she ended up getting a new puppy, and she basically let the puppy shit in her 7-year-old daughter's bathroom. 

A year later they moved into a new apartment. They invited me over a week after they moved. I figured, new place, maybe it'll be pretty clean. Lol nope. I dreaded having to use the restroom while hanging out there. Could barely sit on the couch without sitting on some clothes, or random stuffed toys, etc. 

She sits at home most of the day. 

What makes me feel bad is... I know she has depression, and anxiety. She takes a lot of medications. One of the reasons we bonded initially was that we could relate to each others' struggles. She also states she has fibromyalgia, and has for years tried and failed to get disability for it. 

I've read that there can be a connection between depression and hoarder tendencies. 

Until a few months ago she wasn't working, and I work a full-time job. More often than not she would invite me to come hang out and then ask if I could "please get some beers, been really stressed..." This eventually began to turn me off because she would talk about how poor they are all the time and could hardly get groceries or struggled to pay bills on time, but she always managed to get beer and cigarettes. There was apparently no money, but she was always buying random crap off the Wish app. She would talk about how much weight she'd gained, but she really didn't eat much, she just drank at least one 6-pack beer almost every day. My way of thinking was, if someone needed assistance, I'd gladly get some groceries for them, but I don't want to use my money on non-necessities. It made me feel like she thought I had money to just throw around. 

Sorry if this post is all over the place. I really needed to vent somewhere. I've been trying to cut out toxic things, friendships, etc, that drag me down.  Are these shallow reasons for not wanting to be someone's friend? AITA?
