I went out for a rigorous tennis session, the first real exercise in ages and was quite proud of myself. Thanks to anxiety and panic I had to give up the gym last year and have largely only been walking.
On the way home on the train after the session I started fidgeting, my breathing became shallow, chest pains, my heart rate increased and I had that all too familiar impending doom feeling. It's all consuming and I just sat there waiting until the last stop. Got close to home and was totally fine. No matter how many times the pattern happens it still affects me.
Very frustrating. Even worse is when I go through phases of bad dizziness and chest pains and go to the supermarket. My heart pounds and I just want to get the heck out of there ASAP.
