Hey man, that sucks. Good luck with the friendship bit. This happened to me last February and I'm still trying to get over it. If you don't mind I'd like to proffer some advice with the hug.

You are entering an area of emotional rollercoastering. You'll be up a few times over the next few months and down more often. Cling to the realization that there are better days ahead. Hold on to yourself for you are the most important person in your universe and you have worth. Let your music convey your emotions and let your heart feel them. As time passes the pain does too but hold on to the good times and appreciate the happiness that she brought into your life. Give yourself the time to grieve but then, after a few months, get back into the race.

Best wishes,

Brett
