Why is homosexuality so bad? You were made for personal union with another to demonstrate and manifest on a physical level the spiritual bond in heaven and our relationship with Christ. Homosexuality is a total perversion of that heavenly model.
But did He not make them one, Having a remnant of the Spirit? And why one? He seeks godly offspring. Therefore take heed to your spirit, And let none deal treacherously with the wife of his youth.
Mal 2:15 NKJV

We have marriage also to procreate and fill God's heaven. Homosexuality produces nothing eternal. Souls are eternal. People matter to God.
The truth is, if it wasn't causing you inner turmoil, you wouldn't be seeking affirmation from God or His people.
Please start reading in Matthew, read thru the end of the NT, then start over and read and ask God to reveal Himself and the6truth to you. You are commanded by Jesus( who is God) to follow Him. Not anyone else. He will reveal this to you. Don't judge Christianity on certain people who claim Christian. Why, because if their lives don't line up with God's word, then they're not Christians either.
I saw that you doubt the validity of God's Word bc it condemns your lifestyle. Well, that would not be a good way to judge truth, bc as Jesus said in John3, they don't come to the Light, because they love their sin. Don't worry God is able to keep His book straight, the efforts of many to pervert the message has proven to be a futile and failed effort.
I pray that you open your heart to the truth. God loves you and wants you to turn to Him and be saved.
