I feel you. Try not to put too much pressure on yourself. I've been having a lot of ups and downs myself. Not having anyone to talk to I've been almost by myself for four months with occassional walks with a friend. But the sum total of my human face to face contact is about 4-5 hours a month. This is just not enough for most humans.

Plus there is the added stress that if you slip too much you could end up back into a bad job market. The only thing one can do is to find other healthy diversions and keep diet / sleep / exercise on track.

I hope my managers understand and won't judge my performance at this time.
