If you know the root cause of your depression, maybe try to force yourself to target them and work on them? If lack of social interactions is the cause, force yourself to socialize and hopefully that breaks the mold. Lack of motivation, maybe give yourself some sort of hobby with gradual goals that you achieve over time. Maybe that will help you jumpstart your lack of motivation.
If you're in college, I would think it will have therapist or psych services available to students. And seek more help and advice there.
What goes up, will inevitably come back down. Whoever you have to step on when you go up, you will be at their mercy when you go down.

Enjoy any good things, even the little and menial ones, as you will never know what impending distresses could descend upon you in a moment.
