I have a problem I do not feel up to solving. I am so scared by what I have to do at work that I barely can do it and this thing lasts for some time now. I am so clueless and feeling ashamed for that and my boss is not happy. I managed to even get a promotion and do my stuff so far. But i feel it is getting more complicated and i cannot concentrate and do not feel up to it. Do you have an idea about that? A model I could use?
