It's amazing to me how people really believe illegal economic immigrants to the United States are just like "nah man, fuck the paperwork, trudging my way across a life-threatening desert is so much easier"
I wonder what could possibly create a positive incentive to do something so insane? It couldn't be that getting legal immigration is almost impossible, could it? Surely it's the poor people who are wrong.
Oh wait...
"Because of the numerical caps and per-country caps on certain green-card categories...as of November 2018, there were 3.7 million people waiting in line abroad for a family-sponsored green card, and 121,000 awaiting an employment-sponsored green card."

WE'RE the problem. We simply DO NOT PROVIDE a reasonable legal framework for people who want to come to the United States to do so. They're still here, mind you. So clearly those county-based immigration caps are very effective.
If we want to end illegal immigration, then we need to reform the immigration system so more people can do it legally.
I'm a nurse, not a doctor, just gonna chime in here that non-alcoholic fatty liver disease is a thing:

In general, any kind of sudden changes to your normal functioning are things you should probably be discussing with a physician, even if you're young and otherwise healthy. The really encouraging news is that, if this is indeed caused by a health problem, you're young enough that it's really likely you can completely reverse it and get back to 100%. And if it's not, then no harm done by seeing a doctor and confirming that ¯\_(ツ)_/¯
(Also, not to scare you, but no I wouldn't expect to see that dramatic a decrease in alcohol tolerance over the course of just a couple of years at your age. I think it's worth talking to a doctor about this.)
