Hey,

I can't exercise. If I do some HIIT or running I am getting bunch of symptoms like dizziness I can't concentrate I have anxiety and my mind is jumping all over I'm getting thoughts that I will die etc. How to relearn my stupid brain that exercises are not dangerous? I did all the checks doctors told me I am healthy and can exercise. Yesterday I was on cycling tour with my gf we did 20 miles and near our home I got micro panic attack and thoughts that my heart will stop. It's so annoyed. I see people in the part running I want to do the same. I did jogging 3 years ago 3 times per week 3.5 miles but once got panic attack and then stopped.
