I think I'm having an anxiety attack. I haven't been able to breath properly for the past hour Cuz my chest is really heavy and numb and because of that I started freaking out and I don't know what to do. I tried waking my mom up for help but she told me to put muscle rub on my chest but I don't know how that would help. I really need help on what to do right now

UPDATE: I've stopped freaking out but in still having major difficulty breathing so I have no clue what to do
