Im so tired of this

I slept like crazy today yet still feel tired. I had to lay down for half an hour even. My muscles feel weak and tired, I can’t focus and can’t wake up at a normal time yet often can’t sleep either. I have two months until my doctor’s appointment but thats just to get a referral. Who knows how much longer it will be to actually get help. Id got to the clinic but Im certain it wouldn’t help. Im just so tired all the time and even with soda and energy drinks I can’t feel awake.
