Hey Jambo, welcome back my friend. I can hear your pain. I’ve been very depressed and low and hopeless for a long time in the past. I know how it feels. I am sure many here can relate just as well as me. 
you are right, you gotta keep doing the work, with your therapist, reaching out to friends and support, here for example, there’s so much support to be had here.
one more thing I can advise you is to try and find gratitude for some things, no matter how small. and if it is how good this cup of coffee tastes or that you find the kindness in your own heart to love yourself despite everything just this minute. or that you’re still here, still fighting for that better life you know is out there for you. or that your houseplant is also hanging in there, whatever.
here are some more grateful ppl to hang out with and be inspired by:
Daily Gratitude, The Air Of Recovery #2
you’re not alone my friend. don’t give up. no matter how bad it is now, it does get better, take it from me.
