Get them to check your thyroid levels, that’s what it was when I was feeling similar at 24. It took years for me to feel normal and have energy again but it’s treatable.
I was losing hair in the shower, I had dry skin on my arms and bad dandruff and I was exhausted all the time even after a large dose of aderall in the mornings. My TSH was 20 when it’s supposed to be below 6.
Careful, that is the sort of blasphemy that can get you murdered these days.
