to stay or not to stay

I know staying is the best for me. But I don't even know if I should anymore. It just doesn't seem right. It's two years. Two whole years of my life. What if I'm not strong enough to bear the weight of all the pressure that comes with staying? What if I won't feel happy staying after all? What subjects do I want to take? What do I want to do? What do I even want...? 

I don't even know anymore. Guess I'm back to square one again: I know staying is the best for me. 

After all, there really is nowhere for me to go.
