What comes to me when I read the OP was this Scripture:
"Be anxious for nothing, but by prayer and supplication with thanksgiving, make your requests to God and the peace of God that passes all understanding will keep your heart and mind in Jesus Christ" (Philippians 4:6).
What this means is that you start talking to God about anything and everything. Forget about formal prayers that people pray in church. Many of those don't get past the ceiling. What God appreciates is you being frankly honest and open about where you are at, how you are feeling, however negative that may be, what you want out of life, how to be a real Christian and the person He wants you to be.
When I needed to know God on a personal level, I got out into the middle of a park in the dead of night and introduced myself to Him. I told Him that I needed to know Him personally, or else what's the use of pretending to be a Christian? One moment I didn't know Him, and the next I did. I can't tell you how that happened but it did. Then I started talking flat out to Him, asking all my questions.
What He told me was that to be a real Christian, all I needed to be is just myself, and not to pretend to be "spiritual". He knows me through and through anyway - all my negative and positive attributes. He told me that He would change those things He didn't like about me. He told me to walk before Him and all I needed was to put my faith in Jesus and His finished work on Calvary.
The greatest times of fellowship with the Lord has been when walking along a lonely beach with my hands in my pockets just chatting with the Lord about whatever came to mind. I once asked Him whether He would get tired of my "yakking" at Him all the time. He said that the more He heard my voice talking Him, I would hear His voice talking to me. I found when I asked questions of Him and discussed possible answers, new thoughts came to me which answered the questions, and I realised that He was giving me the answers as I was discussing with Him!
He once told me that He did not consider the Bible as a law book of rules to follow, because as I had my trust in Christ and was talking with Him all the time, He would make sure that kept to the path He wanted me to go. That was 50 years ago, and it has been very true through all the ups and downs, twists and turns of my life. Even when I was living for a while below His standards for me in a particular relationship He told me not to stop talking to Him about it and He would see me through it without anyone getting hurt. And so He did.
The Scripture says, "Casting all your care upon Him, because he cares for you." This is what I am talking about. Casting your care upon God, is getting by yourself and talking yourself out to Him about your cares and woes, your anxieties and fears. He wants to know about them, warts and all. Nothing shocks Him, because He can see them all anyway. So what's the use of hiding your true feelings from Him?
I once asked Him why He wanted me to talk all these things out to Him when He knows about them already. He said that He wanted to enjoy and appreciate me talking to Him about the secrets of my heart, my desires, aspirations. He told me that this was fellowship with Him and He got immense joy and pleasure out of it.
I once told Him that if I found myself standing before Him in the judgment, I would tell Him that all I had to offer was that Jesus died for me on the cross, nothing more. He said, "That's all you need, and furthermore, that's all you ever needed".
If you are unsure about your salvation, there is no harm in going through these steps with the Lord:
1. Acknowledge that you are a poor sinner, deserving of hell, and there is nothing you can do in yourself to make it any different.
2. Accept that Jesus died for you on the cross, to take away the penalty and the punishment for your sins and that you can accept God's forgiveness because Jesus paid the price for your salvation.
3. Ask the Lord to indwell you with the Holy Spirit and do the work of conversion in you so that you will have a new heart and strength to allow the Holy Spirit to form Christ in you so that you will be the person God wants you to be.
4. Receive Christ as your Saviour and Lord, and put your life completely in His hands.
This is more than just saying the "sinners prayer". This is getting by yourself with God and going through those points with just Him and you. You don't have to have the approval of anyone, or any church to do this, because the transaction is between you and God. The church nor any of your mentors and advisers were crucified for you, so they can't do anything for us. It is best to go to the Person who was crucified for you and talk it all over with Him.
Then you can ask Him to guide you to the church where it would be good for both you and Him. Just like Samuel interviewed all of Jesse's sons, and the Lord said as he saw one by one, "This is not the one", but the most unlikely son came in from herding the sheep, and the Lord said, "This is the one". Finding a suitable church is a bit like that. A good saying that I have is: "You have to kiss quite a few toads before you find your handsome prince".
You can go and try out a number of churches, and the Lord might say, "This is not the one for you". Then you might walk into another one, and know that this is the spiritual home and family for you, and you will have a great peace about being there.
I trust that this has been helpful to you.
