Hello Carmen,
Welcome to this board. You will find warmth and support here and you have already taken important steps towards recovery: Making appointment with your doctor and come out of isolation to contact us. I have little to add to the excellent advice on changing medication, but I hope you´ll get stable on meds and start to feel better soon.
I know too well how it feels when the depression is so black, one doesn´t want to bother anymore. Winston Churchill called it the Black Dog, Mike Wallace the Black Hole (if I remember right). I favour the Black Fog. At least that´s how it feels to me, but I find it best to take reasonable action and let it pass.
Best of luck,
