I *think* that it's due to having too much to deal with right now.
I am exactly the same way, for the past week or so. I've been stuck on a teeter-totter, between anxiety and rage. Anxiety feels more socially acceptable to me, but every once in a while...rage shoots out of me, from seemingly nowhere!
A few weeks ago, I'd noticed that my depression was feeling worse. Feeling as though my medications just weren't helping me. I still haven't made a change in meds, but I have spoken with the nurse. Hopefully, he'll make some change/s soon, 'cause this sux!
Have your tried contacting your pDoc for some medical treatment? Has your T returned from vacation? Hopefully, you've gotten to see her and talk about things have gone for you while she was away. If you haven't had that opportunity yet, you could try writing down how your feeling. Without worrying about the words, cursing, or spelling. Just write what you're thinking inside for 20 minutes. That can help some people a lot!
You could try to take your mind off things, through distractions, but it's only a short-term relief.

Listen to some fun, fast music and dance some energy away. Focus on all of the bubbles in the sink as you wash dishes. Marvel at their shapes, sizes, and colors. Smell the bubbles. You don't want to taste them (yuck!), but how do they feel?
I hope one or two of the ideas work for you.
