What are these emotions?

"I can't say I'm scared because I'm, I just don't know if this is the right thing to do for us" I said to him in my strongest vice possible. Allowing the tears to slide down my face .I turned away from him and I said goodbye to him .
With that I walked away from him with tears overflowing. I was always a strong person but when he stepped into my life he change everything, he changed me .
