Dear Jesica,
It's tough moving at your age and leaving behind friends you feel comfortable with. To make new friends, start small. Maybe say "hi" to the person who's sitting next to you in class. Or ask someone a question about homework. You could also try going to an after-school activity that looks like fun since you know you'll meet others who share that interest. When you act friendly and smile, others will want to be around you. Your new classmates are probably curious about you, so be open when they start the conversation.
