CallMeWezzy, You're sure not alone with this feeling!
I'm with you all the way and I think it's very common for Depression to turn into Anger. I feel it's one way for a person to vent inorder to get rid of, or ease the depression.
My brain is going "a mile a minute" trying to think of something that would help you understand and cope with these feelings!
Anger and Rage are an outlet sort of. At least for me. Neither feeling is good of course but I just want you to know that you're not alone.
Wishing I could give you a big hug,
Nanci
