It's never too late to better yourself, it's good that you're starting to take initiative. I was extremely depressed through most of high school, but one of my friends was in a similar situation and managed to get his stuff together, so I was like "forget it" and started bettering myself, got a job, started procrastinating less, and in general became a happier person. Only he took initiative for some girl who didn't want him, and he's all depressed as stuff now because she dumped him over text, but the moral of the story is to better yourself for you instead of some bitch, you'll probably find someone better in life when you're older anyway.
