Alright, I feel like I need some advice. I will try to keep this brief, but that has never been a strength of mine! In summary: What is your advice for "getting by" in a toxic work environment & managing stress? Have you ever been in a work environment where you felt bullied? What did you do?

The (very) long version:

I have my masters in social work. To become a licensed social worker (so that you can bill insurance companies directly, and no longer have to have a supervisor who signs off on all your documentation), in my state you are required to complete two years post graduate work under supervision. My two years will be up in May (by the day, I will complete my hours in April, however).

My plan all along has been to complete my hours before going on maternity leave (which, assuming nothing happens like a premature delivery, I will accomplish), take my maternity leave, and then not return to the agency (dishonest, yes, but I have no problem with it). I will take some time to be a SAHM.

So I have like seven months to go. And I am absolutely, completely miserable at my job. I adore my clients, but the agency is a giant mess. I feel like I am bullied by the people in charge, and have no support (in what is a very difficult position).

I know that the smart thing to do is just suck it up for the next seven months, but I have all this paranoia about what the stress will do for the fetus (and me!), and I really, really hate working at this place.

So even as I've been writing this, I've talked myself out of my first question, which was should I stay or should I go. I know I have to stay. I would feel awful starting somewhere new & then not returning from my maternity leave.
I have never felt so unsafe at a job! I feel like I'm in high school with all the gossip and manipulation that goes on among supervisors! Its really disgusting, particularly for a social work agency!
