Hi Che,
I had to totally distance myself from my mother. She always wanted to argue too. And no matter what, everything was my fault in her eyes. She couldn't be civil for a moment. I don't know what it was with her, she did suffer from mental illness. But you would think when it was your own mother that she would act like she loved you. So I quit going to see her and just left her alone. I lived next door to her, so it was easier. But she eventually started to cause so much stress that it messed with my health. So I had to stay away.
I hope that you will get your cards back when you go back to school. You will be needing them. Being that she is paying for your tuition, it might make things harder. It would feel like you owe her, but don't think of it that way. What does your dad think of all this? Is he in the picture? I would hope that he would be on your side of things, or maybe stays neutral.
One day at a time is my motto. Hopefully she will come to be in a better mood.
Hugs, Karen
