Sounds like anxiety and maybe even panic attacks. You’ve had a lot going on, and the sleep deprivation will make things even harder. Reach out to the doctors, they can rule out any physical issues pretty quickly and they can support with your mental health if you need it.
Sounds like could possibly be related to ur blood pressure. I get that feeling n my hands n my feet drives me crazy especially my hands bc they’ll get real red n swollen n start itching like crazy but I can’t feel to scratch bc they’re numb.
