How to overcome shyness?

Hello everyone. Im 21. Im really shy and how low self-esteem , even though im am considered beautiful and smart , talented. Im very insecure and criticize myself. Because of it I have no one to hang out with. I simply do not ask smb out, cuz im afraid. Waiting smb to text me , but no one does. I really want to have friends, but my shiness is an obstacle. Is there anyone who has the same problem as me?
I really would like to talk to u.
