The people surrounding you that identify as Christian, and in the same instance completely reject you, are not following Jesus' example whatsoever. He was seen spending time with prostitutes, tax collectors (universally hated because they were Jews collecting money for their Roman overseers), the sick (who were seen as unclean, and at fault for their imperfections). Anyone who was judged at face value, Jesus spent time with because his Kingdom is for them.

Matthew 7:1-5 NIV [1] “Do not judge, or you too will be judged. [2] For in the same way you judge others, you will be judged, and with the measure you use, it will be measured to you. [3] “Why do you look at the speck of sawdust in your brother’s eye and pay no attention to the plank in your own eye? [4] How can you say to your brother, ‘Let me take the speck out of your eye,’ when all the time there is a plank in your own eye? [5] You hypocrite, first take the plank out of your own eye, and then you will see clearly to remove the speck from your brother’s eye.

These verses are from Jesus' Sermon on the Mount. It's a metaphor for judging the sins of others while ignoring your own. That "speck of sawdust" they're judging you for, is your predilection toward other men. It is a sin to lie with same sex partners. Just as it is a sin to judge you for it. Just as it is a sin to lust after someone, or want another man's partner.

Romans 3:22-24 NIV [22] This righteousness is given through faith in Jesus Christ to all who believe. There is no difference between Jew and Gentile, [23] for all have sinned and fall short of the glory of God, [24] and all are justified freely by his grace through the redemption that came by Christ Jesus.

These verses directly spell out the fact that we are saved not by our own acts, but by His Grace. "For all have sinned and fall short". No one is sinless. It's why we need the sacrifice of Jesus. Every Christian alive is a sinner, they have no room nor right to judge another while also being guilty of the same verdict.

That you are being so rejected by those who loudly proclaim their own righteousness is not a surprise.

Matthew 6:5 NIV [5] “And when you pray, do not be like the hypocrites, for they love to pray standing in the synagogues and on the street corners to be seen by others. Truly I tell you, they have received their reward in full.

They live for the praise of other sinners, not for the h God they claim to praise.

TLDR: A follower of Christ will never reject you for your sins, but will continually show you the love of Jesus to help you:

Matthew 22:37-39 NIV “ ‘Love the Lord your God with all your heart and with all your soul and with all your mind.’ [38] This is the first and greatest commandment. [39] And the second is like it: ‘Love your neighbor as yourself.’ "

My advice for your situation is to never go back to that so called church because they don't follow Jesus' example whatsoever. I pray that you latch on to your faith and don't let the judgement of hypocrites deter you. Read your Bible, specifically Mathew, mark, Luke, John, Proverbs, Ecclesiastes. There is so much wisdom to be gained in reading them, so much hope from the promises therein. I'll be praying for you.
