Depression does suck @Former-Member but you have got a few things done and that is a positive. I think that we focus so much on the negatives that the positive things we do get passed over. It is a bit like conditioning our children or even puppy dogs - the more we recognise and reward the good things the more they will be done. Depression I see a bit like that - if we start to recognise the good things we do more often then our negative self talk lessens over time . It is by no means an easy thing to do though and takes lots of practice as I we are often predisposed to recognise and react to the negative stuff and then that takes over our lives. 

Losing you support people for a time would be contributing to how you are feeling as it seems that those people are significant influences in your life and when you rely on something that is no longer there it can hit us quite hard. How long will they be away for?
