I started a new job 3 weeks ago. I have done a couple of training courses but I have absolutely nothing to do! I am sitting here twiddling my thumbs. This is having a massive impact on my mental health and I can't stop crying and my anxiety has hit the roof. I left my previous job of 14 years because of a toxic work atmosphere but I would go back in an instant rather than just sitting here. I honestly don't know what to do. I feel I have made a huge mistake. Any wise words?
