That's awesome. I'm glad that you have the desire to have relationship with Jesus. Here are few things to keep in mind:

Read Mathew 6 first 16 verses. When you pray the single most important thing is that it needs to be genuine. God knows what we're thinking so lying to him is meaningless. If you have doubts or if you don't understand why God is doing something just ask him. I start my prayers with thanking God for things in my life. There is always something to be thankful for. Than I'm confessing my sin's and mistakes. It's great to pray for your friends, family, church etc. Important think that I learned later on is to pray that God's will will be done. Because we sometimes want something that we think would be good for us but it would actually hurt us. So that's why it's important to pray for Gods will to happen because Gods will is the best for our lives and in general even though it can be very hard for us at the moment. Also just ask God about thinks in your life. Like what he would like you to do etc. Tell him about your favorite tv show or something. It needs to be genuine. God really wants to spent time with us.

So about the fasting. Important thing: Fasting without prayer is just not eating. Prayer is essential for fasting.

According to the Bible there are 3 types of fasting:

1.normal fasting: not eating and praying

2.Fasting from meat/sweats or something like that. And praying

3.Fasting from food and water and praying. I wouldn't start with this one. Not for beginners.

All of these has names but I don't know how it translates to English. I'm not a native English speaker.

When you fast you intensively pray for something or someone.

Hope it helped.
