As for facing up to the workplace. I had a breakdown a few years ago and had to take 8 weeks off work. I was not looking forward to going back, particularly as I has been a right bitch to certain people in the week before being taken ill.
In the end I asked for a group meeting at the beginning of the day. I explained to people that I had been off with stress and that coming back was really hard. I told them that I wasn't fully better and could be a bit over emotional but that I was on the mend and was able to do my job. I appologised for being nasty to people and said that I was glad to be back, and that if anyone had any questions at any point then please ask me.
The reception I got was good and all of the team welcomed me back. I was treated the same as when I left, except that maybe people were a bit careful to keep stressful situations away from me. The only person who had trouble with me was my boss, and to be fair she was the one mostly responsible for my illness. I won't go into the details of how I was treated right now, but I had enough grounds to take her to a tribunal for constructive dismissal. One thing I do want to stress is that only the one person was a problem. Everybody else was fantastic, and if I'd known then what I know now about life in general, I would have done things differently to help her to understand how to deal with me.
Because of my boss, I felt forced to leave the company so I changed jobs as soon as I could. In hindsight I'm glad that I did as I had been getting stale there anyway and the new job provided me wwith a lot of new and exciting opportunities.
