Sorry to hear that its all getting to you fella.

There has been some very good advice given already. Im the king of the stressheads so probably shouldnt be the one to be advising people. But, you should definitely just try to balance things and if that means saying no sometimes then you've got to do that. Its your life and you cant do all things at once. Maybe try to make a plan of what you need to do and try and schedule your time.

Sleep is the bugger that gets me and Ive really no idea there. I just never want to go to sleep and then when it comes to waking up...well, I just dont want to get up!! Medication is always an option if it becomes too bad but that is just a temporary solution. These days I just try a little light reading for 30 minutes or so. Sometimes I do mange to doze of, but other times Im still awake 1 hour later thinking "Bugger this!". Ive heard camomile tea helps with sleep but Ive found this just makes me need the bathroom.

Anyway, I hope you manage to sort it all out.
