Man, the list goes on and on. And so what the hell exactly are you trying to get at? Everything isn't so clear cut. You can't just say "oh, you're shielding your emotions and that's the problem, so take down the shield, durrrr". That's not the problem. That's not the cause. That's just an affect. The cause is that expressing my emotions isn't natural and when I do it is too shallow, weird, and inappropriate to make the consequences worthwhile.
