Self Confidence

Hi girls,no

i’m 16 and i’m very insecure , all my friends have no problems talking to guys and stuff but as soon as a guy tries to talk to me (mostly at school) even if i don’t like them as more than a friend i freak out cause i don’t have any self confidence , i always think people are judging me.

however, there is 2 guys that are 1 year younger than me and are both so sweet and i’m very comfortable around them even though i just became better friends with them? everyday at school when they see me they want a hug and i’m happy to give them a hug and have a chat but whenever others guys in my year level want to talk or make contact with me in a polite way i freak out cause i feel like i will make it awkward?

so i guess , my question is;

-any tips on how to be more confident

-any tips on how to not be a nervous wreck around guys

would really like some help :)
