I feel like im going crazy....

I'm not going to go too into detail but basically ive always had anxiety and im just now seeing a psychologist about it. For the past 5 days, I've been on lockdown. I couldn't go to school just cause I had to energy to do so. I have so much school work to do and I can't find the energy in me to do so. Last night, I took a 2 hour nap, woke up still tired, after a few hours of being awake, I was still sleepy and couldn't even do my nightly routine because I was so tired. I was trying to go to sleep and, as tired as I was, I could not fall asleep. Eventually, I did fall asleep woke up this morning and im still feeling sleepy. I feel so disconnected, fatigue, lazy and trapped. Does anyone have an idea of what might be happening? Or what to do?
