Thanks for your response. I have had issues with anxiety, but usually they didn't crop up too much unless the depression is/was out of control. Anger was usually not a big symptom with my depression in the past, not like the anger I have dealt with for the past two years.

I guess some of the confusion was also brought on by the fact that I wasn't avoiding social situations at first. He moved out in March of 2014, and for about a year after, I wanted to and would go out with friends, date, etc. And then the desire to socialize just stopped- completely. I wasn't sure if my depression symptoms had changed, or if the depression was intertwining with other issues.
Being a nurse, I know better than to self-diagnose, although maybe that's part of the problem. Nurses have "just enough" knowledge to suspect a diagnosis. And a lot of us dread being diagnosed with something, because we have too good of an idea of what we'll be dealing with.
