ran out of courage

I've changed a lot, and I feel like a different person. I don't know who I really am the more I try the more confused I get. It was a long time ago that I was happy and thrilled, in the last two years I have locked in myself and not bothered about how I feel. but it has started to change there is one person out there that makes me feel good and makes me feel alive. she means a bit but it doesn't matter, because it's just a one-way feeling. and she is not interested. i ran out of courage and I'm scared of being left behind, love is so much more than just feelings but if i can't feel how can i know. take my hand and look in to my heart what to you see? 

I would take a chance if you would...
