Hi sweetheart,
I just want to applaud you for wanting to be close to God and for not wanting to fall away! That's amazing and you're on the right track. Do you know if you've been born-again through the Holy Spirit of God? Have you experienced and do you still experience conviction of sin, and a desire to repent (turn away from it)? Would you say you've ever had a "knowing" that Jesus is in you, that He can hear you when you speak to Him/pray?
Some people, unknowingly, never get truly born again (especially if they grew up in a Christian household) so it's very important for you to ask yourself this question and seek the LORD to know the truth about your spiritual state. But please! Do not fear or worry... even if you haven't yet been born again, you can be born again when you truly surrender your life to Him and ask Him to give you His Holy Spirit.
One of the signs that someone is indwelt by the Holy Spirit is speaking in tongues (but the absence of tongues doesn't mean someone isn't saved). I encourage you to talk to a pastor about your situation or a mature believer in Christ who can help you and guide you.
I'm also here to help you but as I wasn't raised in a fully Christian household, my experience is a little different.
