Emotions bah! I have waaayyyy too many of them and no idea how to deal with the whole sorry mess!
Everyone else has offered good and constructive advice, but I'm afraid I really have none to give.
Usually when I am feeling overwhelmed--which is more often than not!!--I either have one of my spectacularly unhelpful meltdowns or help myself to some Xanax or Ambien.

One strength I do have is my sense of humor. As long as I can hang on to that I have some hope of staying more or less sane, lol! So for me I guess the best way of coping is to watch a funny movie or read something that makes me laugh...or snorgling my kitty

...
Yeah I know. Pathetic ain't I?
At least I can send you some hugs and hope they help!!
