Like some others here say, do NEVER apologize for venting on PT! We are one big bunch of friends here, and we care for each other in good and bad days
Try to talk to your boss, Kirsten. This cannot go on like this. In the end you will have to quit, so he won't be happy with that too . It could be CFS (Chronique Fatigue Syndrome) yes, or what we call here "Glands Fever" (I don't know correct name); but I understand that your problems are caused by all the stress you are under. Trying to relax is most important now! A long nature walk sounds super!
Kirsten do you have the possibility to take some time off? A few days away from work would do wonders for you! In fact, if you are interested, you are most welcome at my place!! We don't live that far apart, and you have a good airport nearby . We are not here next week, but you are welcome any other period!
Take care, okay!! Thanks for telling this story, I was wondering where you were for quite some time already!
