Thanks everyone.
I was thinking about what I wrote here when talking with my supervisor today. I have 4 simultaneous projects, as well as needing to do my own work everyday. She is getting stressed out and I am more concerned for her compared to the work, which I'm doing ok in. I know I wouldn't be able to cope with 4 projects and a panicky boss if I hadn't gone through some difficulties in the past. It is not easy for me, however.
I wish I had something more profound to say, but I've been a busy bee at work, which starts at 4am, time for some rest.
