Meds are supposed to provide a bottom for your feelings - enough so that you don't feel suicidal. Then you can work on the cognitive and emotional aspects of depression and start getting better. As you recover from depression, you feel less tired, less lonely, less bored. That said, I've found that the side effects of medications, or the medication itself, can cause the exhaustion, confusion, etc. that impede my ability to work on the depression.

It's hard to know how much of one's misery is due to the depression itself or to the medications. All you can do is to keep on working on the depression and get the medication changed and/or adjusted. I know that for me, if meds are the reason for my misery, no amount of working on the depression will make me feel better. Chemical imbalances have to be addressed with meds.

If you're taking care of yourself physically (getting enough sleep, eating a balanced diet, exercising several times a week, etc.) and you're making an attempt at dealing with the depression (i.e. meeting someone for coffee when you would rather stay in bed), and you're still feeling like you've described, I would say it's your meds.

Talk to your doctor. There's a bunch of meds out there. You may have to push your doctor to try out different dosages and meds. If s/he won't do it, find another doctor. You don't know until you try.
