I use humor wherever I can find it to jolly myself along to where I know I can support myself/things aren't as bad as I make them out.

Recently I saw a sign I loved:

"Do not reward yourself with food, you are not a dog"

I would read some books on anger and learn about it and practice feeling and expressing it appropriately. Anger is a really good thing; when we feel we have had something taken from us or lost something (person or thing), we get angry, want it back! Learning how to talk to whoever we think has taken it to see if we are correct in our point of view/perspective and can iron out our differences or, realizing that we are angry (with reason) and figuring out how to help ourselves protect better with boundaries or fixing blind spots we may have, etc. are good things to learn.

The sleep thing is pretty much a choice. It does not "solve" anything or make anything better, we still have to wake up and we waste some of that time sleeping. For me, if I sleep too much I am apt to not sleep well at night and then my anxieties pounce on me instead! Thanks but I'd rather learn to deal with things now than have to deal with my unreasonable anxieties :-)
