Idk what’s wrong with me or if it’s just an anxiety episode but my chest feels numb and I keep thinking my heart has stopped and I’m constantly checking on an oxiomoter to make sure everything is alright. I’m freaking out guys. My chest feels numb constant along with my left arm but it’s like an internal numbness, I can still feel stuff. It’s hard to explain. I’m shaking rn and I just want someone to talk to. I have school tomorrow and it’s nearly 4 am and I haven’t slept yet, someone pls help me...
