Hello I Have Had Blood Tests And Both Come Back

Hello I have had blood tests and both come back same ( high cortisol levels )

I have a hospital appointment but it's quite a wait -

My symptoms are -

Shaking constantly but sometimes really intense to point I can't do what I'm trying to do.

I have spells where I sweat excessively and go really dizzy to the point I need to lie down or I will fall down.

I'm always really tired but can't seem to sleep a lot.

Sharp pains through my ribs

Can't gain weight


There some of the main symptoms I have do you have any idea what it could be likely to be ?
