I see two problems here:
-Inertia
-Self-consciousness

Like you said, you have been stuck in a routine for a while without a mean to get out. Combine that with what I perceive as a great deal of self-consciousness from your part - we all are during our teenage years mind you - and that nets you a vicious circle: you think too much without acting on it. Don't bother with the why or the how, chances are you won't find those answers through thinking. It's easier to feel it. Therefore try experimenting things. In short, try to fumble around in the dark based based on what you are currently feeling.

Spontaneity is key here. Have a sensible plan about what to do in life but other than that don't try to plan it.

You'll notice I'm being vague here and that's normal. I think the problem lies within your approach to life in general. By the way, I'm only speaking from experience so don't assume that whatever I say is an universal truth.
