I have had anxiety on and off for about 12 years. Last couple years I have been real good and very calm. This last week though has been extremely difficult. I was having some upset stomach issues which cleared up in a few days with the BRAT diet but every since my anxiety and tension has been so high. Last night I had a full blown panic attack out of nowhere and was problem the most intense one in 5 years or more. It isn't my first rodeo so I do a Decent job at controlling my breathing but I could feel the adrenaline racing through me. Even with my controlled breathing my heart pounded for maybe 20 mins and my muscles couldn't stop shaking. It took to much energy 
Out of me. Now I am work. Drain, tired. I just want to go back to the prior week before my anxiety started controlling my life again.
