If you believe in God and in prayers but

No, I will not lose my faith in God just because of that. God knows what is good for us. Romans 8:28 says that all things work together into good for the ones who love God... Although we seem not to receive what we prayed for, God is in control, and as the Potter, He would shape our lives in accordance to His will. Let God's will be done.

To be Honest with you, I kinda look at it like this God know's before I ever bow my head and pray to him what I need,want,etc. and If I am worthy than I shall receive it. God is walking in front of my life, he is guiding me I am not guiding him. My faith will always be with him.

You can't hurry God. In his own good time, he/she will answer. I think there is always an answer but we sometimes don't notice it. There are any number of ways that God may answer. There is no use giving up or losing faith. What will replace the faith you give up?

Not every pray shall be answered directly, sometimes your prayer will be answered beyond your imagination. Because He won't test you more than you can't bear. Only faith that'll make your prayer answered. So in whatever the circumstances is, don't lose faith
