The Bible says that once you are saved, you are never the same again; you are a new creature (2 Cor. 5:17). If you have gone back to your old ways, then most probably you were never saved (1 John 2:19). If, however, you were saved, then God won't let you stay in rebellion for long. He will deal with you in whatever way is necessary to bring you back into fellowship with Him.
Did you become a Christian by going to church or by asking Jesus to forgive you of your sins? The latter makes you a Christian, the former doesn't.
You don't try Christianity to see if it works, or if your life gets better. You receive Christ because you trust what he has done for you on the cross so you can escape the judgment of God upon you for your sin.
