The war on emotion: feelings as a sign of craziness and vulnerability

I'm an avid tumblr, and an avid advice giver. I find that when I'm reading someones blog post or letting a friend vent to me I seem to find them apologizing for getting emotional, or for expressing how they feel. They feel ashamed of their fear, haunted by their sadness and scared of their vulnerability. Everyone has emotions, and everyone should be allowed to feel how they feel, and even more so express how they feel and share it with those they care for. But recently this line has been drawn, especially in my generation, that only a certain amount of feeling is acceptable and beyond that you're irrational or crazy, unstable and incompatible. 

How sad is that though for our generation? That girls today are pushed into thinking that their feelings make them weak, and that their own vulnerability makes them undesirable and incapable of being accepted by those around them. I know for myself that I am incredibly passionate in all that I do. I dive in heart first to everything I do, therefore making myself vulnerable. And I've been hurt so many times do this, and yes, it hurts. But do I regret being passionate, do I regret the love I have for people and those around me simply due to the fear of being hurt again? No, I will continue to be passionate. I will probably also continue to set up walls, walls that I build to protect my heart while still allowing myself to be vulnerable to those that really deserve my heart. 

I know I'm going off on a little bit of a tangent here, but what I wanted to get at here is that emotions are real, and powerful and life changing. Where would we be without them?
