sounds like how i get, i can have spells of being fine, then for no reason i feel really down, i cant explain it, i really wish i could. best thing if you are concerned is to go to see your doc and have a nice little chat with them and see what they think, after all its what they get paid for!

hope ya feeling ok, im shattered, just got in from a 12 hour night shift and thought id look on here, take care.
