I get what you're saying. You can't share everything at this point and its wise of you to recognize what types of conversations you all can manage.
Also, I can honestly say that I identify with the burnt out feelings! They certainly come in a long-term issue such as yours. What I've also noticed is that those feelings will pass as well and at a later point (sometimes days, sometimes hours for me) a new energy comes around and keeps me going. I hope you can rest up from the emotional fatique and get a second wind soon!
