Hello I’m 19 and I have terrible social anxiety, especially with girls.

If I buy something from a store and have to go to the cashier I get extreme anxiety and if it’s a girl I turn all red and my voice goes away.

And if a girl only looks at me for longer than a couple second I get red and anxious.

I’m about to go to college and I can’t miss as many changes as I did in high school because I was so stressed of girls.

Can someone recommend me some thing to get rid of this
