Backstory: My mom has been ignoring me out of nowhere for the past four days. She has ignored me before (for getting a B in a college class she didn't talk to me for over two weeks) I'm now a graduate. She also ignored me for over a week when she called me but I didn't pick up (I just hadn't heard the phone as I was eating at the time) Recently, she was laughing and being friendly and close with me (asking me to go shopping with her, frequent conversations) and we haven't had issues for the past 5 months. She started ignoring me after she demanded (with a joking voice) that I clean but I told her I needed that time to study since there's no other quiet time but I will do it as soon as I'm done. I said it respectfully. also, I always clean whenever she asks and if I say I'll do it, I do it. I also cook and am a homework helper for my younger siblings to give her a break. 20 minutes later after she asked she cleaned up herself and left to pick up my younger siblings alone even though we'd always go together. I called out her name and called her on the phone twice with no response. Three days of silence later I tried to break the ice by asking why she's ignoring me. She said "hm" and nothing else. I asked again... No response. I waited a few minutes and asked if she will answer and she said "leave me alone" I said I can't believe this is happening and I can't forgive her for this one. She said "I don't care". I said alright and she said "okay bye" she didn't look at me once. She acts normally with all of my other siblings but makes me feel like a ghost. She doesn't acknowledge me or even call me to eat as she does everyone else. I'm incredibly heartbroken since I've always been the one to protect her and this is a huge slap in the face. I've always done what she's wanted and I'm still treated this way... I feel like I'll never get her approval and she makes me feel like an insignificant, worthless person.
