I'm done

*EDIT: Thanks to you all for your kind and caring posts. As one commenter said, thanks for being willing to share your own experience so we can all get other's perspectives and ideas. I know the world doesn't owe me a living or a meaning, I know I need to get off my backside, I just hope I can eventually do it. Cheers.*

Male, 56, professional. I've lost all enthusiasm for my profession, and seems I've lost enthusiasm for most things. I quit my job and the thought of getting any job at all seems overwhelming and unattainable. I feel I've lost my edge, mentally. I used to enjoy travelling and tramping (which I used to do hard-core), but I don't have the motivation anymore. The most I can enjoy is slow days looking out the window, and doing a bit of work in my garden.

Luckily I own my house mortgage free. I do have some tens of thousands in the bank, but I'm not really set up for retirement.

Anyone else the same?
