Why do i find it so hard to get drunk?

F 20, 56 kg, 5’7

I’ve always found it very difficult to get drunk. In the past I’ve had a ridiculous amount of shots only to feel slightly tipsy. Last night I had around 10 different drinks, a few shots of vodka and 5 mixed drink shots within roughly 3 hours. Felt absolutely nothing. It was honestly sad and I eventually had to force myself into the mindset of a drunk person to not feel like the only sober one lol. But what was so confusing was that a friend of mine was completely smashed despite us having the same amount of alcohol. We are roughly the same in both weight and height. And I know it’s bad for you but I also ate nothing before drinking so it would hit me faster.

Does anyone else struggle with this?
