does quitting something hard to pursue better opportunities elsewhere make me a weak man?

I am in the navy on a submarine and i hate it. i mean really, really hate it. i have recently been diagnosed with clinical depression due to seeking mental health treatment after a series of deaths occurred in my life, and i am likely going to be given the choice to a) seek a waiver to fight to stay in the navy, or b) go to med board and be medically separated. in my mind, i should strive to fight and do hard things, but i have always dreamed of going to law school. Would quitting the Navy in this case make me a weak man? or am i just moving towards something better?
