Breaking free

I need to confess something my boyfriend broke up because of my low self confidence, I was socially awkward, insecure and shy.

People would ask us to go out I would say no because I feel like I'm not as perfect as everyone I'm not the prettiest not the smartest it would give me headaches at how much I beat myself up I would put on outfits and feel insure even though people would say I look great I would freeze up and not know what to say to people

Can you please give me advice how I can talk to people feel more confident
