Congratulations on a job well done. I understand how hard it can be to get on top of things when suffering with depression. Maybe having the "after" photos blown up bigger and put near the door might help. Even if you only manage to put one thing away today it's a start. It will be nice for you to sit at your new machine in your "like new" sewing room.
I wish you happy quilting but also future wellness. All the best wishes from one who has been there.
