You're always gonna find people like that, no matter where you are. But those people don't really matter. The best thing you can do is not let them get away with it. If someone stares at me, I give them a huge smile or blow a kiss at them or something to let them know what they are doing is wrong. Or say it's not my fault you find me attractive.
But sometimes it's just about the area that you live in. Like if you lived around me you could find quite a few people that would not only like you for who you are but admired you for being yourself. Come move to Belgium. But it's best to not let people like that get to you. Cause they are prolly hiding something about themselves, that they are too afraid to let everyone know. Almost everyone has their secrets that they are ashamed to admit. Those who make fun of others are usually the most insecure of them all. So acting like what they say doesn't bother you and turning it around on them really gets to them.
You need to meet some new people. It's hard for your friends, cause they've known you for so long as being someone else. But a new friends will only see you as bella and as a girl. It's just a different feeling, and it's really nice. Just find some other girls that seem nice and a bit chatty, and just be honest with them from the start. You'll be amazed how far that can take you. You can always pm or if you have discord, I have a group of people that I talk to who from all around the world, that are very open minded and lovely people.
