I am sorry for all you are facing. I have phases where I loose hope. At those times I just try to get through the day in the best way I can and try to comfort myself in ways I can.
Do you have family and friends to support and help you?
I am sorry about the foreclosure. Have you looked into disability?
Are you able to see a therapist or psychiatrist? I have severe insomnia and that with the high pain,anxiety,I could go on is a very bad cycle. I have tried meds and am on them but have you for sleep etc?
I wish I had more to offer. I hope things look up soon.
