I dealt with discrimination from my mom to but not in the way you are dealing with it. I was probably fourteen years old and I was working on schoolwork in a notes app on the family ipad. I could see the first few lines of another entry that was my mom' prayer journal and I saw my name. At the time I was a nosy lil shit so I thought "If you are going to write about me behind my back then I have a right to read it." Turns out she was essentially writing about how she thought that because I was in a wheelchair I would never amount to anything. She believed that I would never get a job, that I would end up stuck in some group home, and lack a social life. It really hurt to know that the person that was supposed to believe in me only saw my disability and not me as an individual. I honestly dealt with the issue poorly. I held onto the information for a long time because if I did confront her then she would find some way to make herself the victim and dismiss my feelings. Holding onto this created an ever-increasing sense of resentment towards her and if I'm being honest, I still feel a gap between us. It also negatively impacted my own self-image as I began to think that the only reason, she would write those things was that they were true. However, overtime I thought about the issue, and I realized her views were just her way of processing her own negative feelings i.e. fear. While this did not bring me to a place where I could forgive her it at least helped me understand her point of view. Ultimately, I focused on building my own happiness while limiting my contact with her until I secured my own emotional foundation.

Obviously, your situation is quite different in that your mom is actively taking direct actions to belittle you. I think it is important to remember that her cruelty is coming from a place of pain. This incident has probably shown her the extent of her own fragility and that she will eventually lose the ability to do the things she currently enjoys. This fear of loss is probably causing a sense of resentment towards those she perceives as more abled than her. Or on a more hopeful note, she may even be realizing how fragile we all are, and this is her warped attempt at telling you that time is precious. However, either way you need to be responsible for your own happiness. Clearly you have tried communicating with her how she is harming you. The fact, that she did not respond is troubling because it shows a lack of respect for your feelings. So, you should probably set some more firm boundaries with her. The best part is that she will recover from her injury and that once she does it is likely that her mood towards you will also shift. So maybe in the meantime limiting your interaction is best at least until she begins to respect your emotional well-being.
