I know that I didn’t work through other stuff that needed doing when I was gambling, because the gambling was all consuming of my time energy and emotions. I hear that you have a lot of emotion towards your boss and I wonder if you can find a safe way to let this out. One method I have found useful is to put your energy into beating up a cushion (large beanbags are good!) You could give the cushion the same name as your boss and then have a good rant – letting have it with everything you’ve got and calling her all the names under the sun.
Of course it would hep if you did this in the privacy of your bedroom – or maybe with a trusted friend to support you (NOT your boss though!)
It will make you feel better – but the important thing is that it will clear your head – and you may then be able to find a practical solution to your work problem that is there but your “seeing red” head can’t get to.
You ask what to fix first. I would say yourself. You have already made a start with the gambling and it is still early days. See your recovery through until you feel stronger to face some of the other stuff. You can’t be there for your daughter if you go back to gambling – so if you want to help her, make that your priority. There’s probably more I could say – but I will leave it there for now … you know you have this forum to check in with.
