I am still going to pray for your salvation. The Lord doesn't want any of His children to fall to the temptation of the devil. I know it might be hard to imagine you'll be happier with Christ, but it's true. Any positive emotions you get from the devil aren't permanent. They will die when you die. If you trust in Christ and follow him, the joy and hope you feel will stay with you always. With Jesus, you will never need more. Nor want more, for that matter.
"I am the way, and the truth, and the life. No one comes to the Father except through me." John 14:6
