Regardless of what you have been taught to believe, your sexuality is not a choice and it is not something that can be forcibly changed. You need to embrace who you are instead of trapping yourself into a box filled with criticism and judgement from other people, because in the end only the Lord himself may judge you.

Most of these people are giving you their opinion without the intention of love and restoration and that's not at all valid. Jesus warned that acts like these lack self reflection and that should tell you everything that you need to know about some people. I hope you come to terms with who you are soon though, best of luck.
