Recently (very recently) started a new job, its a completely different role to what I was doing before (although I do have some previous experience) and I'm finding it really hard to find my feet. I realise its early days, but I haven't felt this 'out of sorts' in a new job before. I feel very overwhelmed. Not sleeping and constantly thinking/worrying, esp as I will be left on my own very soon over a very busy period. My previous job, albeit wasn't 'easy' (no job is) was very much like you've done your shift and when you've finished, its done, there's no taking it home with you. Whilst the people i work with in my new job are very lovely and have been really good with me, i miss my old place and the simplicity of it. I am pretty sure if I was to ask they would take me back but would I look stupid? they got me some lovely leaving gifts and I would feel guilty about that.
