How to stop overthinking ?

Man how to stop overthinking 😮‍💨 ? Lets admit it there must have been some moment where u did something embarrassing 🤦‍♂️🤦‍♂️. Then how do u stop overthinking about it. I always keep on thinking - "what will this xyz person think about me ? then they will tell their friends about how much of a clown i am ? Then this information will spread and one day everyone will know that i am a clown😭😭" All the guys/girls pls help. Some people suggest that let it go but then how will someone make friends if everyone knows u are such a embarrassment 😭😭
