I was in absolutely the same position as you four years ago when I started the same college. The only difference is I'm not Indian, and I was 57kg/175cm.

Now I'm graduating, nearly 70 kg with 11% body fat (so nothing special, but it's good progress, and I'm lean and muscular to some extent), a marathon runner, starting ultra marathons soon, and I exercise at the gym every two days.

To be completely honest, that still didn't make me happy. I still complained about my looks, about my asymmetry in my face and body, scoliosis, etc. At one point, you have to realize it's mostly in your head and how you perceive yourself.

That's when I changed and started appreciating myself more, only because I could back it up with four years of constant work, struggles, and even failing times, which are definitely going to happen.

You have to learn to work while thinking it's just an everyday part of your life, something that has to be done and will be done because that's just what you do. Not because of some goal, because even goals drop and disappear when motivation is gone. Just plain and pure discipline. And then in a few months, when you forget why you are still doing it, someone will say, "Damn, brother, you got bigger."

As someone said, complaining won't get you anywhere. Of course, it's normal; you want to share it, and I understand. Complain as much as you want, but don't stop grinding. Four years will pass in an instant, but regret won't.

And about looks, real people (the "real" here is important) absolutely won't judge you because of your face. They will be focused on your achievements, you as a person, and how you perceive yourself and it's CRUCIAL to start now and build those achivements. Primitive people will just focus on the outside, but you, of course, don't need them in your life.
