Hello I'm new

Hi all I have just discovered this site. I have been anxious and panicked the last two days and desperately trying to navigate my way through this episode. I ha e anxiety, depression, PTSD, adjustment disorder, eating disorder and body dismorphia. I think that's it, oh and a sense of humour . That's it I think now. I feel I am desperate to work out a way to cope with work after extensive work place bullying. Now I'm in a different workplace with same company, different manager [who has worked with me before and would be aware of my experience] now what I am facing is trying to navigate my way through a new manager worker relationship, trusting I'm not going to be bullied again, not be triggered, know (identify)when I'm being over sensitive to what may be a normal worker managger interaction whilst being able to ascertain my current experience is normal, no hidden agenda, not out to bully me/get me, be able to trust what im being told i.e offer of support.. trust said offer is genuine and not a guise to set me up... how do i differentiate between what is genuine behaviour etc and not start of a bullying process through punitive issue seeking behaviour. Basically i dont trust i will be safe treated fair etc. So how do i turn my thinking around and my response. I feel so desperate to do this. I just want to go to work... do a job and feel safe. The thing is i want this new situation to be different, how. Do i ensure that when a manager raises an issue as an issue and does not raise it in context eg a task not completed and no acknowledgement, the worload/lack of resources/ redirection do others.tasks etc... I get and think I may know how to deal with that approach to them raising an issue , however any suggestions greatfully appreciated.

What i want to know is how doo i stop or deal with the kneejerk/instant internal response i.e flight or fight.... I just don't want to have the anxious triggered response and then the emotional/ thinking/psychologixal/internal spiral effect eg issue raised-body/mind response(fight flight adrenalin )-anxiety/worse case scenario/catastrophe-thoughts and spiralling to thoughts of what if i loose my job house etc. Especially when this has been an experience i have had through unfair dismissal process (not lost house but it is my fear as a single person n limited support. I want to be able to deal with this without crumbling,,, i want to deal with it in a way i dont make myself a victim,,, i want to deal with it differently, ie be more assertive less fearful more feeling of personal strength. I want to feel i can do this and there wont be retaliatioon ir unfair treatment buklyung etc. I have written a lot here for a first post. Im hoping by doing so i might learn some tips dealing with the situation in a less emotive triggering way and aldo im trying to reach out get a comunity support around me so im not alone. Im so use to to doing it on my own and i want to change how i operate. . , thank you for reading
