How to deal with toxic mother?

[Michieex]

Any time I try to have talks with my mom (who lives a few states away) she constantly shuts me out. Like she even goes to the extreme of blocking me on Facebook and ignoring my calls whenever I try to talk to her. Like I am back in school and asked her for help towards my school bill and then when she told me she didn’t have it I told her it’s ok and I’ll find a way. She then went on to say she’s going to call my dad on me to say I’m harassing her for money and wrote on my Facebook saying why do I keep harassing her. She then blocked me. She gave my brother’s girlfriend $150 and is sacred to ask for it back but with me her own daughter my mom treats me like I don’t belong. Even though I am in my 30’s I suffer from depression and it’s like my mom could care less. She knows when she needs favors I’m always there for her but she can’t even have a simple mother daughter talks with me and it makes me feel like why me like all I try to do is be a good daughter to her and she treats me as if I’m a burden

You are an adult. You don't have to deal with her at all.
