I used to be you. Dont do it, there are so many good things to live for and things change. Hope this will help you. But I lost most of my hair(like patchy balled) at the age of 17 due to the stress of being undocumented. I found out late sophomore year of high school and the implications of being undocumented. I was embarrassed that I cant drive like most of my friends. All of the hard word studying for college was wasted knowing I cant hold a regular job. My close friend who I confided in about my status left because he doesn't want to hang with dirty undocumented(he's a legal Hispanic). I worked odd jobs after high school for couple of years then DACA came along. Similar situation, somehow I had this hot white girl all over me at a point when I had DACA. Couldnt go with her to Denmark to clap her cheeks so some Denmark boy ended up clapping her cheeks. I thought my life was over.

Homie, only 10 years later. I got my citizenship through work. Married the love of my life, multiple degrees, recently bought a house, own several new BMW/Tesla cars, 7 figure NW, got into skiing, traveled to many countries and dined/stayed in some of the most expensive hotel/Michelin places around the world. I'm well respected in my line of work and gave my parents green card.

I cant promise you things will get better, but you gotta fight. Fight hard and find every bit of chance to get papers and get ahead. Dont throw the towel in now, because it means all the pain and suffering you have endured was for nothing.
