HIya, I know about this emptiness and I especially know about the disconnectedness. That's my speciality. I feel so disconnected from people sometimes I'm almost afraid they're not real or I'm not real.

It sounds like you are completely fed up with your way of life, stuck in a hum-drum routine and living your life completely for others. Is there any way you could scrape together an hour or even half an hour to do something for yourself every day?
Perhaps just to go for a walk and enjoy nature or catch up on an old hobby you love or used to love. It might not feel good at first as is the way I find with depression but I think you can gradually begin to enjoy it again if you stick with it.

I hope this helps a bit
yours, goggles x
