Hey! Well I've decided to start exercising in hope to help with my anxiety as I'm starting to get very depressed. I've read that exercise helps the mind. I have major health anxiety, mainly worry about my heart. I had an ECG a few months ago which came back clear. So tonight I went for a mile long run. Wow am I unfit! But I'm determined to keep going. But now I'm home lying on my bed I'm getting chest pains in only one area. Under my left pec. I'm not anxious as such but a little worried if the running had anything to do with it?

I'm a 19 year old male. Ex smoker and drinker. About 13 stone, a little over weight not really noticeable.

Any help please!
