Nervous

I didn't know what to do and so I wrote a letter, a four page letter pouring out my pain and honestly to the one that had been my best friend for the past six years. I feel like I need to go to his house and talk to him, the letter was suppose to be a back up plan in case he asks me to leave. I feel like just giving him the letter would just be a good idea to go give to him. I'm confused, what do I do? Do I be brave and release my energy? Or do I coward out and give him the letter possibly not knowing if he will end up reading it? I need help.
