Being made fun of

Hello Everyone,

This one is an ugly truth for me,

I’ve made an ass of myself more times than I’ve had protein and veggies for dinner.

There was a time I tried to pretend in front of my friends that I could be the Wolf of Wall Street and got laughed out of the interview due to not being able to explain derivatives.

There was the time I went out with friends and threw up on my friend’s couch after having a single shot of Tequila.

There was the time I did my first public speaking gig and messed up a speech about my own life which I’d rehearsed over 100 times.

I guess you would have understood how i feel, the thing that messes up with my mind is the flashback of these times whenever i try a new thing, can someone explain what can be done to overcome this?
