I started a new job a few weeks ago and I'm worried I'm going to regret it. The plus sides are shorter commute, a pay rise, and some nice colleagues. However, they don't do the same role as I do and there is no one to really explain to me exactly how to do my job. I am qualified to do the job but haven't worked in this particular area before so feel quite inexperienced and could really do with more supervision (it's a specific area of healthcare). People have very high expectations of me and the requests are piling up. I don't know how to stay on top of things. I have a constant knot in my stomach and I'm not sleeping at night. I want to be able to do the job properly. But also I want to cry at the thought of having to go to work tomorrow. I feel lost and don't know what to do. I left a job I liked to work here and I wish I hadn't.
