Dear Nanamar
It may not feel so, but please believe you are not alone. You say you are not religious and I can not give you faith, only each individual is able to find that for him/herself and be open to the Lord, asking for help.
Be assured, Jesus is by your side, even if you are not aware. Why not, in the quiet of your heart just say the words, Heavenly Father, I am tired, and I am worn. I feel pressure from all of these circumstances surrounding me, please give me strength and guidance. If you are truly there, allow your peace to calm me in my current circumstances and give me the courage to face these challenges.
You have nothing to lose by trying.
One of my dear grandson's can not walk, talk, eat (tube fed) and has many other complications since his early infancy - it is hard, especially for his mother but you should see the bond of love between them. He is now 13. Even in his suffering, Jesus is with him and I know one day all will be well .....love conquers all and it is how we live our lives that helps us on the path to Heaven, our true home if we so choose it.
Faith is not easy especially in our world today when so many Christians are persecuted. When you learn how much suffering and pain they go through it often brings home some of our tradgedies. I know many people who have been helped through prayer.
I do wish you well and that times and situations will improve for you. x
