Sorry in advance, lol. This is going to be a long post. Here is a little bit of a background, my mom use to be heavily into drugs for about 5 years straight, last October was her one year mark of sobriety. She had my baby sister in November of 2015. She has managed to get and (keep) the job as of now, it's been two or so month. She is the type of mom to asks her kids, especially myself, for rides or  to borrow my car to go to work(she doesn't have a car) money for cigarettes, but she always uses my baby sister as an excuse because I would help her if it was anything related to my baby sister. My mom had been living with me for a while before she had gotten an apartment and barely got a job not too long ago, so tax season came up in January for me. I am employed but she was barely working at the time. My mom wanted me to claim my baby sister and her too. So I did because even though she barely started working the money could benefit both of us. She had agreed to let me keep $1000 which was more than fine with me because I didn't need the money as much as she seemed to need it. Anyways, last week she called me and asked if I could take her to town to get a new van key made because her cousin is letting her use her van and my mom accidentally broke the key off in the door so I agreed to do so. After I took her to get the key made she asked me for a ride to Safeway and I said in a calm voice"this is why I get annoyed doing things for you, because you ask for one thing and keep asking for more, even after I just did what you said needed to be done." She got very angry and started yelling at me in the car saying to just drop her off right then and there, I wasn't going to do so because my baby sister was in the car too. As I was driving her to Safeway she told me that I couldn't keep my share of the tax money and if I did she was reporting me to the IRS even though she had let me claim her rightfully so and now she is being spiteful. I was hurt because ever since she has been sober I've always been there to help her with diapers, baby food, gas, basically anything. I've even let her use my car. She texts me everyday asking about the taxes since they are in MY name and asking if they have came and they haven't, but she won't leave me alone about it and she keeps insinuating that I've already gotten the money and I'm just not giving her her part(which is not true) it's irritating and hurtful that even after I've helped her so much she still does or says things like this. She cares more about the money than anything, and it makes me wonder if she's back into drugs again?😠 I don't think I want anything to do with her after the money comes. Parent or not, I don't feel like she genuinely cares about my siblings or I. After what she has put us through(addiction wise) I think this was the last straw. Any advice on what to do from here? Or similar situations, and how you handled it? Thanks in advance.
