First day back to work and I'm overwhelmed already.

We're going to have company vacation. It should be nice because we're fully paid for that, not for work, and it's somewhere I've never traveled to. Unfortunately, work is the source of my depression and anxiety right now. Moreover, I've been shunned by a group of coworkers. I know can stick with other groups, but random room division will be dreadful. I wish I won't share my room with that group.
