But what if what depresses me is out of my control and I'm having an extremely difficult time dealing with not only the situation but also the fact that there is nothing I can do to change it.

Also some of my depression is for no reason at all, I just feel depressed.

And then there are times where I start to really self-loathe not only myself but my entire life, more than I usually do and would really not like to be.

Three different scenerios that all result in depression. I don't think they can be all handled in the same way.
