I know what it is like to not have the mental energy to do the things you know might help. When in a severe depression I do them and they don't make any difference anyway.

At least you are going to work each day. that is huge. I have had periods where every ounce of energy I had went into going to work each day and performing at a high level. After work and weekends I was spent and had to recharge just to do it again. You would think that getting lots of exercise at work and doing a very good job at my foreman duties and making the boss money would be enough to lift me out of it. The fact is it took enormous amounts of psychic energy for me to be able to do it. That was when it was moderate depression. Severe I can't make it to work.

I hope you can get your meds straightened out and feel better enough to use the other tools you have.
