Since the beginning of March I've managed to get myself running and can now run 5k without stopping. I should say I'm about 18st and a size 22. I have been feeling positive about being able to run 5k but in the last two weeks I've had two nasty incidents of passerby shouting quite hurtful things to me and the last two times I've gone out for a run my heart just isn't in it any more, and I just give up. I just don't want to be the punchline of a joke, and make a spectacle of myself. Reaching out for some words of encouragement please...
