I need advice.

Rebekah

So my mom is an alcoholic and she has been for years since I was about 13. I'm now 24. I currently live with her and financially support her as well as my sister, she is 16. I'm just tired of seeing my mom drunk every day and its makes me really depressed. She also is really manipulative and I'm starting to resent her a lot. She will my sister and I she is going to kill herself if we leave the house and she will take my car without asking when she has her own to go to the liquor store. A couple nights ago she wanted to buy alcohol but I only had 20 which was to take my sister and I to work/school. So she got really mad and told me that she is just going to take her, but she will run out of gas so I will have to put gas in her car anyways. She only wanted gas to go to the liquor store. That's exactly what happened. I just dont know what I'm supposed to do or how to handle this. I feel really depressed all the time, resentful and guilty, because I dont want to be so angry at my mom. I feel like a fucked up person for not wantng to take care of my mom or let alone speak to her anymore. What makes everything worse is that my mom is involved with a CPS case with my sister. I just dont know what to do anymore and I feel like I'm under a lot of pressure.
