I know what has triggered it, I'm trying to battle it but this time with no safety blanket of job security.
Last year I was signed off with anxiety/depression/stress due to my horrible, bullying boss and unsupportive colleagues. During that time as well as receiving counselling, ADs (which I never took and am now against), I also applied for new roles. Got to the last stage for a few and then got rejected which seemed to highten my anxiety and stress.
I decided then to just try and recover, I returned to work but my boss was still as nightmarish as before and I won't give reasons on here but was made redundant.
I'm now trying to get a new role and it is once again getting me really down and anxious. I have been for numerous interviews in the last month whereby I seem to get the good signs and then bam, the rejection. I hate the rejection, it's like being dumped.
As I said I'm trying to remember my counselling techniques but I can once again feel the blackness and insomnia returning. Cant believe I'm still awake.
I'm not sure what I want other than some reassuring words. I am starting to feel empty, it's so hard to shake off the rejection

I appreciate you reading this long post, hard to share in RL as friends and family have their own issues to deal with. Thanks.
