Depression Support Group
Depression is a real and debilitating condition that is often misunderstood by family and friends. Its meaning can range from a prolonged period of sadness to an actual mental illness with specific symptoms. Find and share experiences with others who are going through the same struggles.

I think that is maybe natural? I am in the midst of difficult times with my SO and boy I can be filled with such anger sometimes, so much bitterness and blame, and honestly I feel a little relieved by it because it seems to replace the blasted depression for a little while. So I revel in it just a little bit, while not acting on it of course, because it can be nice to feel something other than sad, self loathing, and guilty for a little while.
Ideas off the top of my head:
Writing angry letters (let it all out!) and burn them
Listen to different music than usual (angry music!)
Journal.
Run instead of walk.
Good luck!
I have trouble with anger . I find myself uncomfortable with knowing the difference between being assertive and aggressive. That makes it difficult to know what is alright to do in response to being angry. Sometimes you can choose to let anger go; other times, you need to take some action. Even if that action is just to choose to sooth yourself.
Good luck.
