So recently I've decided to start running with my partner, and every time I run for more than a few seconds I get very anxious and feel like my stomach is turning.. Like the feeling when you know something exciting/scary is about to happen. Except I know that there's nothing exciting or scary about to happen. I think this somehow stems from my school days as every time I ran in athletics/cross country events I always felt like this but 10 times worse, and I feel like my brain thinks because I'm running I also need to feel anxious. I've tried concentrating to try and stop feeling this way but it only works for a bit and then the feeling comes back again, and keeps getting worse and worse until I have to stop and walk. I have taken up running a few times before this and I remember having this feeling, but I don't remember it being this bad and making me stop. This is very irritating because I want to exercise but find it almost impossible Anyone experienced this? Or have any suggestions how to fix it? (I know I could just find another form of exercise but my partner enjoys running and I wouldn't have the motivation to do anything else really). Thankyou
