I thought I was the only person that felt this way! I used to be a runner in high school (I'm 24 now) and then college took care of that! Now I'm working--and it's cold all the time--and it getting out of bed in the morning is tough. I've had a thyroid test--nothing there--and blood tests--again nothing. I think i might just be the weather! This winter has GOT to end soon--for all our sakes! Kepp us posted Lana Marie--let us know if things get better for you when winter ends! And, do try yoga--even if it's low impact--it's a start (and it's SO relaxing)! Good luck!
