How do you make friends when you lack personality?

Whenever I'm in public, I just notice so many people have friends and it makes me feel that people who have depression or anxiety. like if they just had friends. They could share their problems and get positive feedback or even encouragement from them maybe boost the confidence of someone. But I guess that helps or doesn't for someone.

I feel like it's my fault that I'm not putting myself out to others and really being my true self. Because all I think is what if this people think I'm weak person or they recognize im carrying too much insecurities or read body language and I'm viewed as someone that doesn't have confidence and self belief.
