Advice Please

I (17f) got diagnosed with MS 4 months ago and I feel helpless to say the least. I have no idea what's now supposed to be normal and what is not. I often experience numbness and tingling in my limbs. I used to have the sharpest memory but now I'm lucky if I can remember a conversation I had with a friend a few hours ago. Has anyone else struggled with this? I also just finished my second round of Mavenclad pills a few days ago and start physical therapy next week. Advice, experiences, or opinions on any of those?
