I will give you the straight word of God on the issue of LGBT and you can take it from there.
Leviticus 18:22 Thou shalt not lie with mankind, as with womankind: it is abomination.
Also read Leviticus 20:10-21 and Romans 1:18-32 as to what God has said about the unusual use of our bodies.
There are no tips on prayer and healing, but only what the word of God says and that we are in Christ and He in us through the Spiritual rebirth from above as we walk in newness of life indwelled with the Holy Spirit.
Prayer is very hard for some people as they do not know how to pray or they think there should be some grand format to follow to make a perfect prayer. Some are even afraid to even approach Jesus as they feel he is unreachable in their lives for the way they live, but Jesus will hear the prayers of anyone who has a sincere heart for the Lord no matter who they are and in all boldness and a humbled heart will come before His throne of grace.
Hebrews 4:16 Let us therefore come boldly unto the throne of grace, that we may obtain mercy, and find grace to help in time of need.
Hebrews 7:25 Wherefore he is able also to save them to the uttermost that come unto God by him, seeing he ever liveth to make intercession for them.
Praying is humbling ourselves before the Lord and making a petition before him in simplicity of words for whatever our need is. Jesus, as our mediator, sits at the right hand of God making intercession for the saints of God as he presents our petitions before the Father. You do not need eloquent elaborate words or long prayers that use vain repetitions like the Pharisees used as God called them hypocrites because they were arrogant in their ways loving to have others see them in such formality who made the outside of themselves look good, but were nothing more than full of iniquity.
Prayers consist of faith, consecration and commitment.
