The trouble with chronic depression is that it's chronic. You do get depleted from having to pull out of it over and over. I know that firsthand. But you pulled out of it, in the past, when that was hard to do. You probably can, and will, pull out of it again.

Start small. Maybe just shower and go to the store. Get yourself some special treats. Pick up something nice to have for breakfast in the morning. Then let that be part of what helps you get up tomorrow. What you've done before, you can do again. Some days, we have to be satisfied with doing just one constructive thing - just one thing.

Hope you feel better. The rest you've taken was one you needed.
