There is a history of depression and anxiety in my family and with my DP.
In the last week I've been experiencing heart palpitations that last hours. This in itself has started to worry me that I'm experiencing some sort of anxiety attack. I thought i had no other symptoms but now i think i might be getting short of breath for periods when it happens but this has developed as I've been getting more concerned that things must be getting on top of me even if i haven't realised
Do panic attacks last this long or are they usually quick episodes? I could be jumping to conclusions because of my awareness of anxiety.
