God loves you Najira - don't forget that! I think it would be really good for you to pray and ask God to help you, and to talk to other Christians who could pray for you, maybe in a youth group or church. Then you should show unconditional (never ending) love to to Idalia, because that will show you're loving, forgiving and not mean or spitefull. I don't neccesarely mean you have to love/fancy her, but be nice to her, be friendly, ask her how her weeks going etc. Ignore the male to female, female to male comment as God loves you regardless of your sexuality/past
