Shifted to a new firm in December. Was on a three month sabbatical before that because of workplace stress. The old boss has gotten too critical and personal and I couldn't cope. At the new place, the people are nicer. But the role demands too much and I'm constantly struggling to finish things. There's a lot on my plate which I'm doing the first time and I'm worried I'm failing. I'm not able to sleep well, be happy and even on vacation I'm thinking of work and what's left. I've already contemplated leaving and just sitting at home at avoid this stress. It's crippling anxiety and I need a way out.
