I just want to improve myself, how can I do so?

Don't get me wrong, i train 3 times a week (even tho in november i used to train 6 times a week, so kind of a downfall), i have good hygiene, i'm kind of good in school and i have many friends.

I've just went through the roughest breakup of my life so far, and i feel like i need a change, what can i do
