Have you been more tired lately? I know that lack of sleep can really affect me. With all these changes and being busy, you're probably needing some rest.
I find that I don't adapt to change very well because of the OCD. I'll go through more racing thoughts and a bit of depression from it. I just got married, and it's a huge change for me. I'm sure a bit of time will also help you adjust.
It's good that you're trying to talk it out, too.
