dating/confidence/hoe tips a tricks

Ok so I was in a relationship with a guy for FOUR years. Started dating sophomore year. Now I'm newly single and ready to start hoeing. I'm slightly confident online but honestly in person I could convince you a blade of grass is more attractive. I need helppp, what do you do to boost confidence or how'd you get comfortable dating? It's hard bc I'm small and have the body of a 12 year old boy but honestly I need advice. (Picture for reference)
