R/Advice

Hi! I’m sorry if this post is jumbled as I am very flustered and at a loss. I need advice when it comes to communicating and making it quite clear to an individual that she needs to get their shit together without losing her friendship. To preface this I am a 24 y.o. F who recently took in my friend (21 F) and her young son (3 y.o.) due to some family issues that put her and her son in danger. We have been friends for 7 years. Everything to start was going well. We initially agreed that she would help with bills and pay for groceries. She helped with the groceries but had no money to help with anything else. Then the problems started to arise. She stays up late, goes out, and then sleeps in, leaving me to care for her 3yo son. She can’t get a job due to not having her GED and apparently can’t get a GED because she has a DUI charge. (So she’s not helping on the bills at all). Today she had her mother’s vehicle and was parking at my house, in front of my garage. She backs in and as she’s getting super close to my garage door. Like within inches and you can see that we were in the red on the backup camera. I got nervous and I stated ‘Hey watch out for the planter’( it’s right by the garage door) She gets a little flustered and we laugh it off and I just told her to be careful. She was flustered and said ‘oh I thought I hit something’ She began to I guess repark (pull forward) and instead She fully backed into my garage door. She seemed apologetic but there was no real apology only telling me that she’d ’bend it back into place’ I was very upset as I am struggling heavily in this economy and can barely afford to live let alone fix a garage door. I saw the damage and rather than freaking out on her I left my house. I came back afterwards and let her know that it’ll probably cost at most $2,500 to repair the damage. She got irritated with me and stated ‘There was so much chaos and if you weren’t talking to me, it would not have happened’. That obviously upset me because what do you mean it’s my fault? I wasn’t fucking driving! I chose to hold my tongue and she then stated, ‘ I guess I’ll go outside and get pictures since I guess I’m paying for it.’ I need fully mature advice on how I handle this. I know that if I say anything not thought out right now that our friendship will end. Please help me. Thank you
