Take things one day at a time. And don't feel guilty about taking some time for yourself (playing games). You NEED to do that.
It's the oxygen mask in the airplane. You put YOUR mask on first, THEN put the mask on for your loved ones. Why? IF you try to do them first, it's harder, and takes longer. If you take too long, you might pass out before you succeed, and then you both die. You take care of yourself first, they might pass out, but will be ok after you hook them up.
So, DO NOT feel guilty about doing little things to make yourself feel better. It's needed. And HAS to happen, or you'll crack up and won't be good for anyone.
I don't have a commission in your queue -- but if I did I'd tell you to get to it whenever, I care more about the PERSON that the artist is more than my commission. And it sounds like you've got a lot going on that needs to be taken care of.
So, take care of yourself, and just keep moving. it'll get better.
