any tips??

so in two days i start highschool and i’m really nervous. i have really bad anxiety which i have been dealing with sense i was 3. i really don’t have any friends and i don’t know anyone in my lunch time. i don’t know what to do and i don’t know how to feel confident with myself. i also have no idea where i’m going because all my classes are in different wings. does anyone have any tips on how to make and keep friends, or tips on highschool in general?? also if anyone has an coping skills to help with anxiety i would appreciate it
