My with and I fought tooth & toenail against Pancreatic Cancer for 13 months. Our Faith, family and friends provided our strength. I too found it difficult to talk face to face with people.... so I sent an almost daily email which detailed our progress each day, to all those friends wanting on the mail list. It was my daily 'medicine'. I was therefore able to avoid repeating the same story over & over which can be a chore and depressing and people knew how to best assist us when we needed assistance. Additionally, I refused to consider my plight in all of this; while there was so much as an ounce of hope, my focus was entirely on my wife. I could wait. I think that helped avoid depression along the way.
I find now that she's gone Home that depression sneaks up on me. In my view admitting our falling into occasional depression is a big first step. It's a normal part of life, don't give into it and don't deny it; embrace it. Seek help if it's overpowering. Don't be ashamed. The good Lord made us this way. It's a relief valve. I'll pray for you and as Churchill said "never give up"
