Hello Outlaw: I wish I knew what to tell you about this... I don't.

I'm an older person now. But I've struggled with anger issues for many years... a lot (but not all) of it directed at myself.

Part of what my anger issues involve, as it happens, is also a move my parents made with me many years ago; & the unforeseen trouble the move brought down upon me. (I'll spare you the details.)

To this day, all these many decades later, I'm still angry about the whole thing, even though I know my parents could not have foreseen what was in store for me.
Anyway, the one thing I know, as a result of all of this is that repressed anger is corrosive.

It can lead to long-term depression (as you already know), anxiety & learned helplessness. So I hope that in some way you can figure out a way to begin to dig yourself out of this dark place you now find yourself in. Hopefully being here on PC can be of some comfort & support.

I wish you well...
