My mother has MS, is her behavior normal?

My mother has multiple sclerosis. In the past, she has often been disinterested in things that were important to me. In things that were important to her, like grades, achievements, sports, she was very interested and only then did she usually show that I had done something really well. She also complained about things when I did everything right, so she was always defensive. And less emotional, doesn't give as much praise or hugs, I don't live with her anymore and gets in touch, but not like my mother, more with normal things like good night… And most of the time, when I have ideas, she says, no, don't do that, because… and that makes me feel like she doesn't trust me. And she tries to control me a bit by asking if I've already learned something and should start, even though she should really know that I like learning and that I can be relied upon to do it.

She also tries to push problems away. I don't know if that's her personality, because it's very stressful, or if it's part of the MS. She never talks about it, and she doesn't go to therapy or anything. Has anyone had a similar experience?
