I don't even know anymore. And I'd hate even more to go to the hospital and find out they're not even that bad and I've wasted my time and money. I don't care about myself enough to seek medical care either. I don't know.
Oh god right, I forgot your healthcare is expensive :(
Maybe start with trying to get yourself some pedialyte. If you don't want to spend money on that, then just trying to find foods/drinks in your house that have decent levels of sodium, magnesium, potassium, etc, might help with your sleep.
Again, not a doctor here. Not sure why you can't sleep. I know that you're worried about getting checked, and I get it.
Although I *really* doubt that if you went to the hospital that you'd get normal blood work at this point. Don't let that worry stop you from going to get medical treatment.
