Good morning Cathy. I'm very sorry to hear of your struggles with physical and mental issues, with the ex abusive relationship and with the loss of your husband.

I too have these phases when I feel that things are all bad and I just can't take it anymore but then the next day or week arrives and it's not so bad anymore. It affects many if not most of us who post here and I just can't tell you how much support and love everyone on the forum gives. We all understand because we've been through it.
Sometimes it's not just as simple as us being able to get over it by ourselves. There's no reason to be embarrassed when you speak to your doctor as that's what they are there for even if at times it seems they try to rush you through. You might consider speaking with a therapist though as they're better trained to deal with emotional issues and thoughts while family docs are better trained to deal with physical ailments.
I'm happy you turned here to post and wish you a well and peaceful day. Please feel free to PM me if you need/want to chat. I'm here on and off during the day and evenings so if you see a green light under my name, I'm here.
All the best and welcome.

Chris
