I'll pm you the links in a few x
I definately think as the weeks go by and you start to feel better physically and see some weight go, you should definately get your CV up to date and register with some employment agencies xxx Get that working life sorted as it is too big a slice of life to be miserable in.
Just wanted to add this as I was thinking about it further, you say about it being a bad time to change jobs, but I think it could be the perfect time, you were brave enough to go for an operation to change your life as your weight is one of the causes of your unhappiness and discomfort, well your work is another major cause of your unhappiness by what you have said. Why not just be brave again and get yourself out of the situation?
Any downsides eg a pay change etc have got to be overshadowed but getting away from this negative person who's undermining you and your self esteem.
I think it would be a positive step to cut loose and go somewhere new, meet new colleagues and be yourself and stand up for yourself from the start.
Don't tolerate the crap because you feel you aren't able to get something better. This could be the start to a whole new better phase of life, together with the band helping you to cut the weight x Please have a think about it and get that CV out there to some good agencies online.
Even if you don't immediately find something, just knowing that you're declaring yourself available for new jobs and have taken steps to find one should have a really good psycological effect on you and how you cope with work and the cowbag boss from hell till something better turns upx
The anxiety is a signal telling you this situation is not good for you and you need to change it. The anxiety will not go away until you address the cause..eg your job!! Rather than try and suppress your anxiety use it for what is, the trigger to change things for the better x
