I think sometimes I just need a 'splurge' day. Today wasn't too bad.
Aquacise was brilliant - great fun, very silly and hard work all at once. For once I don't feel completely knackered and depressed after counselling, which makes a very nice change.
Shell you are right - the key is exercise. It has really cheered me up, although I don't think I'll ever be fit enough to do your kick boxing, as I am far too lazy!
