What does it feel like to get shot?

what does it feel like to get shot by say a 9mm, in the stomach. i've had recent issues and have been threatened to be shot. that being said, i'd like to know how to deal with the pain IF i do get shot. i don't know what i would say about myself when it comes to pain, when i was younger i would wrestle with my dad, we'd get pretty rough, and my parents would say i like pain, but when i THINK of pain it makes my stomach upset. i've never been in a real fight, and honestly i think the most pain i've ever fealt in my life would be when i ripped my thumb nail off. that was when i was younger, now i'm 18, i can tolerate more pain, but i'm not sure how much... i heard and have read that if you get shot endorphin's are released and adrenaline shoots through your body, and it numbs the pain almost to where you don't feel anything between that and shock. please, serious answers only.
