All prayers got answer in a right time. What i am doing is jotting down all my prayer request in a paper and keep it. Since God know all your prayers once you submit it to him, its done. Sometimes you already got the answer you dnt notice like no, yes, and wait. Just remember if it is no, then it will not bring good to you. Much better is happening. Things you seeing not you want only directs you to the right path. About accepting Jesus by your gf's parents, also takes time. They must know what Jesus has done by reading the gospel , from there they will have relationship with Him. Also it starts with you.. They must see you being Christ like and soon they will get interested reading about Jesus.
God bless you.

Amen

We all go through in this kind of feeling. I am alone but i know God is with me. Communicate with God ..it is a form of prayer. There are more ppl fighting for cancer in order to live. You are lucky to have life, just live it right .. Feelings are temporary
