I often find it difficult to share my thoughts

I'll admit. I am often fearful. Not because I fear pain or any physical harm. I am afraid that damage to my heart would destroy my soul. Something that I have tried to repair over time. My damaged soul. Ripped, and shredded. I understand that I am extremely sensitive and often seem very needy. With that being said, I open up only to specific and a special kind of person. Why , is it seemingly easy to just replace me? I mean, sure. I'm difficult to understand. So unique that it is extremely scary to open up to me. 

What's a glen to do.
