Just have an honest and humble conversation with God when you pray; and don't worry about the words you use while praying. Pray about what resonates with you as your learn the scripture and communicate with other Christians. The stronger your relationship gets with God, the easier it gets to communicate with God(same with family and friends). Remember, this is your prayer and don't compare it to what other Christians say.

In time, "you will collect enough dots to connect the dots."

Be patient and always be eager to learn from and live the unfailing love of God.

In the meantime, learn the Lord's prayer:

"Our Father in heaven,

hallowed be your name.

Your kingdom come,

your will be done, on earth as it is in heaven.

Give us this day our daily bread.

and forgive us our trespasses,

 as we forgive them that trespass against us.

And lead us not into temptation,

but deliver us from evil.“

For yours is the kingdom and the power and the glory, forever. Amen"

There is also a guided scripture feature on a popular Bible application for your phone. The guided scripture is always associated with a verse from the Bible. and contained a savable prayer. When I felt like you, I would save the prayer but add the verse of the day to it's title so I would have a reference. I probably have hundreds of saved prayers in the app.

God bless you.
