Losing the plot

So who would've thought not being able to exercise due to a totally stupid injury would affect me so badly. I have well and truly fallen off the wagon and fallen apart. I'm not sure how to kick my arse back on the wagon but I really need too before this spirals out of control. Been out of action for 4 weeks already and been told its another 3 months yet of therapy then and only then can i start to introduce my exercise classes back into my life. 3 months? the thought of it has totally crushed my motivation. Then being told it could be three years before I'm pain free has sent me into a chaotic whirlwind of destruction. But.......I know where I have gone wrong and I'm trying to drag myself back into the zone. Have cooked on mass today and planned all weekly meals and fingers crossed for a loss this time next week. Avoid the cakes avoid the chocolate and avoid the bread (as my psoriasis is now coming back with a vengeance too) who'd a thunk a bad week could affect your body so much. Feeling crap crap crap.
