hi suzette,
you're apparently doing all the right things on the medication end; taking them religiously and staying in contact with the doctor. so that's good if you plan to continue taking them.
for me, i know what you mean about them "not working"...i've always viewed meds as just one of the tools i need to use to stay out of my depression (or to grow through depression to some degree at least).... i will assume you are doing other things as well like going to the doctor, trying to excercise or walk, eating as healthy as you can, and gtrowing your social life as much as your able too, and perhaps writing, and others.
it's so hard to do the non-med tools when i was feeling down; they're even hard when the pain is relieved!....
i appreciate your sharing about this. may you know that your not alone.
i send you love and kindness
