Adjustment disorder, stress, panic attacks

Hi, I have been experiencing workplace bullying, I stood up the managers, I did not realise how much the bullying was affecting me. One day I had enough and called them all the names under the sun, I was sent off to have a mental health assessment done, severe stress, anxiety and adjustment disorder. This was all caused by a change of roster dispute. A simple solution was there, but they refused to help with two shifts I had family commitments with. I am now changing stores, of course a new roster has to be done, I have legal help, but already I can feel the anxiety and stress building up. I have already disputed just one shift, they then came up with a different roster, which is so far from what I work now. HR know the stress etc I went through, they know it led to adjustment disorder, they have the mental health assessment.

I feel I am going to break down again, I need to work, but I feel the company is no help at all.

Any tips on how to stay calm, I don't want the levels of stress and

anxiety I have already been through. I have legal help, they say they are there to take the stress away.
