Although I have never been in your situation Yuri, I was in a pretty bad place a few years ago when my wife became very ill (potentially fatal),and spent months in hospital and I had 3 small children and was working for an ar##hole company that refused to help and give me any time off.
We are all different, but for me ATG was a real help. I certainly stopped replying to threads/group buys etc, but having an hour or so a day dipping into other people's lives/jokes/excitement made me realise the world keeps turning and it took my mind off things for a short while at least. For me this helped.
I hope you are in a better place soon, and if so keep popping back, even if you don't have the energy to contribute!
All the very best.
