(((Ixodon))) sending hugs!
I know EXACTLY how this feels, especially about feeling that way about work! I am in the same boat, I've applied for loads but nothing. And I know what you mean about feeling empty, I feel that way a lot too - like I've lost the ability to care about anything any more. What helps me is trying to find a way to make myself care again - I look through a family photo album, or go and explore somewhere new, or get an adrenaline rush from doing something exciting. I hope you find a way to make yourself feel a bit better
