See a therapist.

I'm serious. You need to nip this in the bud sooner rather than later. I realize that there's no "magic sentence" to snap you out of your depression, but I've been going to college since 2011. I only recently transferred to Iowa State from community college as a sophomore, this semester. I'm 25. I let depression smother me, and the older you get - and trust me, the years start flying by the worse your depression gets - the harder it is to make up for lost opportunities.

See a therapist, get yourself on meds, do whatever it takes to claw your way out of this hole. Force yourself to go to clubs, even if you'd rather stay in bed all day. I get it, it's infinitely easier said than done, but the sooner you get a handle on things, the easier and more enriching your life will be.
