i sometimes have very random nervousness. so i looked online and i truly believe i get panic attacks. i am 20 years old. the last one i got was at my job at the end of the day while i was counting the money in the cash register. out of nowhere i got very nervous/anxious, my hands were shaking pretty badly, my mouth was very dry and i had trouble breathing. it lasted about 10-20 minutes. i tried to control it but i could not. i dont want to lose my job because of it. and now i get nervous about the next time i have to do that at work, i feel like i will have another one so im continuously thinking about it. i talked to my doctor and he said its probably my personality. i know that it is not, im not a nervous person but since about a year ago it started happening. what should i do?
