It's only been two weeks so if I were you I would give it some time. Toxic work environments are not easy to handle and they do tend to stick with you afterwards. I've been there.

Making this post is a start at healing, so kudos to you. I'm going to point something out that is a personal preference of mine. I never facebook friend a person I work with. I have several facebook friends that I've worked with in the past, but never current co-workers. I know several people who do the same thing. I also do not indicate my place of employment on my facebook profile.

Good luck with your educational pursuits!
