Idiopathic hypersomnia

I’m 16 and have been struggling with IH for a while I was first diagnosed more than half a year ago and I’m struggling when I take wave I feel like it doesn’t help much and I’ll sleep 10-13 hours consistently and when I am up and tired I’m constantly mixing up names of people I may have known for years and my short term memory doesn’t work and for at least 8 hours after waking up I just feel horrible tired and anxious and it’s just constant teachers and coaches don’t understand so it’s always a battle trying to explain why I miss a class or why I fall asleep on accident or just can’t get work done any tips on how I can help with symptoms
