Please help my wife and I

Mental illness could have an impact on your life at any time. It slammed into ours 6 years ago and since then I've been trying to deal with everything as best I can, pretty much alone.

My wife used to laugh, help people, go shopping with friends, have nights out.
For years now, she has refused to leave the house, she won't even go as far as the gate.
My wife won't even come for a walk up the street with me when there's no-one around. I've tried to persuade her many times but with no success.

Unfortunately my wife's job was our main source of income after work for me dried up some time ago, so her inability to function due to this horribly debilitating illness is having a devastating impact on our finances, especially the mortgage payments.
We can't sell the house to raise money because she won't leave the house.

Asking for help or reaching out to people is not something with which I've ever been familiar or comfortable, but I don't know what else to do.
We would really appreciate any help you feel you could give.

Thank you for caring.
