I think I just ruined my friendship with my best friend...

To make this short and sweet I'll do bullet points:

-My best friend of 7-8 years

-She's a party girl, I'm more reserved

-Moved in with her in August to help her out as her parents gave her a deadline to move out (they're not great parents)

-Bf moved in to to help pay rent (split three ways)

-Fast forward to November

-My depression is at an all time high, so is my anxiety

-I don't enjoy living with her

-She brought her two cats without paying for them (or even telling the complex) while I paid for my cats to live there

-She drinks occasionally (is underage)

-Smokes weed

-Is horribly messy and never picks up after herself

-Today: I told her I'm not happy and I want to move out

-She guilt trips me saying that I would f*** her over and she can't afford half the rent/cant afford a studio/doesn't know any couples/etc.

-She just unfollowed my boyfriend and I on Facebook and Snapchat

-My boyfriend texts her and she basically says I'm not her friend anymore

Am I in the wrong? I feel terrible about this whole thing, what do I do..?
