Sorry you've been suffering. I'm wishing you love, health and the ability to create happiness for yourself and others.
Depression is a terrible thing. I've had it myself. You think it's never ending, but that's part of its spell.
I found great solace in getting out into nature. I was able to meditate (just be quiet and let thoughts come and go, not holding onto any of them - observing them as if from a distance.)
Volunteering in a garden for a few hours a week gave me exercise, light and quiet. That gave me the head space I needed to accept the company of others.
It's hard to feel compassion towards yourself, and all too easy to speak to yourself incredibly cruelly. As an exercise, it's worthwhile thinking of someone you like and respect, and sending them kind thoughts; then do the same for a stranger; then someone you really don't like ( everyone seeks happiness and tries to avoid suffering); then do it for yourself. Practice feeling compassion. Don't forget to include yourself.
I hope you find what you need.
