Please give me the strength and faith to keep going

Dear Lord please give me the strength to not give up. Please take all this sadness away from me. I feel so alone on this earth. I only have my kids and I’m scared that I let them down. I feel unworthy of being loved. My parents never showed me they loved me so there must be something wrong with me. Everything is falling apart. It was a mistake for me to be born. Please help me. I don’t want to live this life of pain anymore. I shouldn’t be here. Yesterday was my birthday and I hoped I wouldn’t wake up but I did. Please Lord take this painful life I’m living away from me.
