For the past 3-4 months I've been struggling. I'm not as productive as I normally am, I sometimes just sit at my work laptop feeling completely paralysed. I lie awake at night worrying about work, who I spoke to, things I've said, roles/responsibilities. Then I struggle to get up in the mornings. I don't do anything in the evenings and barely do anything at weekends. I eat crap and keep putting on weight. I can't bring myself to do exercise. I feel terrible.
I was recently moved to a new team with a great boss but wasn't given the promoted role I went for. There are two others in the team who did get this level of role but one is on maternity leave and the other is working notice on her existing role. So I've been covering their work and not getting to my own. Boss is aware of this but there's been no let up since July. I turn this over in my head constantly.
What should I do?
