I'm in the same boat as you in terms of how I use social media. Tumblr allows me to take a backseat and watch everyone else do things as i reblog their posts.

Yay, school! That might help you feel a little more at ease with where you are in your life, having a goal to work toward n all. I'm going back to school in the fall myself and it helps me feel like im not a total lost cause.
