Is this a case of depression?

Anonymous
I'm 18 turning 19 soon to be a college junior. Lately i've been feeling sad... i go to sleep late, wake up late, been bumping heads with my entire family, sometimes i don't feel like getting up from bed, i have nobody to hang out with, i feel like crying out of the nowhere. Yet, i have no SERIOUS reason to be depressed. Why is this going on?
