Im not stuck up! im just shy and scared..since i lost 100lbs?

You look great! I wouldn't have ever known that you weighed more. Looks like you've worked really hard. Be proud of yourself. Have confidence. You're a very attractive person. I don't think you look "gay" because to me you just look like a person. Even if you do act bi or whatever, don't be embarred by it, embrace who you are. Once you are comfortable with yourself, you can start enjoying your life without having to fake anything. When someone talks to you, talk back to them, they are interested in you and want to know more about you. You have nothing to lose by acting like yourself. Don't doubt that they would like you. Have confidence in everything you do. You'll make friends. Open up!! I know that some people might make fun of you for being bi because some people are just mean like that, but those people are the ones who don't matter. You will find people who don't care. You have to take chances to make friends. You can do it. Just be friendly and honest. Maybe there is someone in your exact shoes, taking a chance by talking to you, hoping to make a friend. :)
