It is a very small company only 4 employees including the owner. There are some business partners who are not directly involved. They were told of his behavior and were honestly not surprised. Apparently his temper is well known.
... I actually moved here because of this job and now dont want to get out of bed in the morning.
Isis, I'm so sorry for your situation. This year I finally got away from an aggressive and hostile work situation, and a lot of what you say sounds horribly familiar.
Do you see a therapist? It sounds like you wanted - understandably - to leave your PTSD triggers behind, but unfortunately we carry the effects of our experiences with us and can find them wherever we go. For me, working with my therapist on what was happening specifically at work, and the meaning that had for me given my history, was necessary to help me through the situation and even find some healing in the process.
In my case, if I didn't look at what was going on in the context of past abuse I was at risk of moving from that bad work situation to another bad one.
I agree with others that the only good option is to find a different job. I recommend beginning to look straight away, because the longer you're in the situation it will erode what self-confidence and self-esteem you have, warp your perspective and exhaust you.
If it's an option to move back and rely on the support of family and friends for a while, or perhaps get a "McJob" (something to pay the bills rather than a career move) for a while, I think it's worth considering things like this. I understand the need to support yourself, and don't recommend doing something financially reckless, but if there's a non-abusive option that isn't ideal but gives enough financial stability that might be a good thing to do for now.
To help understand and deal with the situation while I had to, I found the late Tim Field's website helpful -
Link Removed. Its old and the legal information is specific to the UK, but the way it looks at the phenomenon is relevant. It explained and normalised a lot of what I was experiencing especially the pages on why people bully (ie, act abusively) - [DLMURL]http://www.bullyonline.org/workbully/bully.htm#Why[/DLMURL] and the other links under the heading of that page.
You're especially vulnerable because your new, you're away from home and comfort, it's a small organisation, and you have PTSD. Please be realistic about what you can achieve and what you can cope with. I know we should be able to enforce our rights, and things about your work situation probably contravene state or national employment law and regulations, but something that Tim Field says which I found very true is that it's pointless complaining to people who have authority and responsibility in the situation, because they're precisely the people who are already ignoring it and don't want to deal with it.
So, I think all you can do is protect yourself as best you can, get away from the situation as soon as you realistically can, and look at it with support to understand the dynamics in relation to your past experiences, and how to heal that.
