After taking a long break from work (almost a decade) to raise kids, I somehow got a job back in my original career, despite not having kept up to date at all with the industry. I went back, barely able to use a computer anymore and they assumed I was able to use complex programmes. Needless to say, I've been on an extremely steep learning curve and live in constant fear of being 'found out' and feel like a total fraud. I'm working in a large fast paced office with lots of very knowledgeable people. This week I've been using a complicated programme that was afraid to admit I last used 21 years ago. It's obviously changed a lot since then and I'm making very slow progress. Im only in 4 days a week, so feel at a disadvantage to keep up with other staff, but I can't manage my household and family if I do any more work. My self esteem is at rock bottom all the time and I feel like I'm going to be fired. What can I do or how do others cope in a situation like this?
