Maybe it is just scrutiny, but most people who are homosexual by their nature are lesbian or a gay man, often intelligent, very smart, and brave. Somehow, they are stand out from other people, not just by their homosexuality. Maybe you have noticed it too if one of your friends is gay. Gay people are gentle beings that will never tell you a bad word. They are not falling in an offensive state. Even if not accepted, they are staying more human than many others are. So, firstly, you should embrace who you are. If you're a lesbian, you're definitely not a bad person. Your choice, your way of life is nothing else but just living. You don't have to be afraid of other people thinking that you and many others are mongrels because this is not true. Nor you should be upset for those people, consider them like not open-minded. The second step is learning how to be brave. You are special, and you don't have to be someone else. You are just you. Don't be afraid to share it with your loved ones. This is a heavy step, but nothing will make you such happy as understanding that your family and friends accepting you, and you don't even need to lie to them about "boyfriends." It won't be easy. Indeed, it may be painful as well, but only for the first time. Maybe they will need time to overthink things, but they will make their decision to accept you, be sure of that.
You don't have to follow this trend with gay coming out. If you just want to love and be loved, leave it for people who want to fight it out. Earlier or later you will have your own coming out. Just stay yourself at all times and don't be afraid. You're definitely not alone.
