We are trying to work out if it is a thyroid thing or if, perhaps, you are in some sort of manic state. If it is a thyroid thing, all it takes is a simple blood test to find out and if they do find it is your thyroid, they’ll run a few more to narrow down exactly what is causing it. Very simple. I take medication for mine. It could be neither and you have probably slept for hours and hours since you wrote this.
If you are in dorms, go and see your RA. If you live near your parents, let them know how you are feeling. You may need to see a doctor if it keeps happening.
We need sleep. It is how our brain has time to do it’s information filing. If you don’t do your filing, the information piles up all disorganised and before you know it, you have a shambles of information everywhere and can’t remember where your own name tag is. This is why sleep is so important for learning and retaining information.
