Heart condition & exercise/tiredness?!

FHelenD

So I'm 23 and have an artificial heart valve after having septicaemia and an inflamed heart in 2009. Before that i was really fit and healthy - only 18 years old and about 8 stone, healthy diet and did ballet 4 days a week!

After my illness I was super unfit from being bed-bound for so long, even getting out of a chair made me out of breath. So I slowly put on over 2 stone in the past 4 years and really wanting to shift it now and enjoy exercise as much as i used to. Only problem is that i'm exhausted most of the time - i have to have 10 hours sleep a night because 8 hours just isn't enough. And i always fancy going jogging but i cant do much - its about 60 seconds of jogging followed by 5 minutes of walking etc.

Anybody else got a health problem that they have to battle agaisnt with exercise?
