I don't think you are lazy. Not at all. I do that number as well. I get up in the morning and say I will get out of this recliner and accomplish X and I'll keep moving. Each day passes me by and I sink further and further into depression. I think that's one of the great lies of depression.
I hope tomorrow you do get off that couch and accomplish something. That would be a victory for all of us. Please don't beat yourself up if you don't. Maybe someone else on this forum will have an answer. Thinking of you.
