Maybe you should ask yourself if you're on board with a god who doesn't want you be happy and who you are. Sin is a made made construct to control people. So in your god's eyes, is it better for someone who is gay or bisexual to be "good," compassionate and kind or is he more on board with someone being hateful, angry and oppressing but gets off the hook by admitting to they're a sinner? I'd consider moving towards the first option.
