Male Baldness Info

My parents keep joking with me that i’m going to go bald, and that really scares me!
First of all, i know nothing about either of my grandfathers. I know that male patter baldness comes from the mother’s side.
My mother’s younger brother is bald (but they don’t have the same father)
I have been looking at old pictures and my hair line has always been kind of high. Just recently since starting college have I “noticed” any differences. I’m EXTREMELY stressed and i’m dealing with depression right now. I tend to freak out about things.
I’ve been sick a bunch of times this and last semester. Should I plan on going bald or should I just focus on getting myself back together over the summer?
