Does anyone else use exercise to control their depression? I have to exercise regularly or I find myself slipping under again. Have just had flu and am feeling post-viral ( achey joints, very tired ) and I can just feel myself sliding again. Also, have recently been diagnosed with a foot injury which means no running for atleast 2 months - this was my life line and I'm feeling a bit panicky right now. I am absolutely desperate to start exercising again, even if it's just a dvd in front of the tv. I am totally fine just as long as I am fit, totally not when I'm not.
