I'm sorry to hear about your husband. It must be really hard for you. Depression does trap us in our own head. I've suffered for years, only to feel I am just existing. I, too, am all my daughter has so I must keep going. I know you must be lonely with no friends and as our bodies age they also trap us in situations we can't help. I'm sorry you can't find a way to get to therapy because I think it might really help. Being on PC is a good way to make online friends and that can be a big help. Are you on any meds for your depression, if so maybe they need to be changed. If you are not on any meds you might consider seeing a doctor about that. I've had to be off mine for a while now due to medical conflicts, so I know how bad it can get without meds. Good luck and keep posting.
