All I can say dude is just stand strong and try to keep a positive outlook on life. I lost my best friend 5 years ago who was like a brother to me. One day we were hanging out joking about the fact I bought a beetle then the next day I found out he lost his life in an accident
It hit my gut like I was the poll his car slid into... dropped myself to a hole and never wanted to come out of it. then came to realize he wouldn't want to see any negative come from events, he touched way to many people in a positive way for me to bury that. I'd be lieing if I said I'm over it, because it still hits me at times. But it's life, a short and bittersweet experience and while at times it kicks you down the only thing you can do is stand up stronger. do whatever it takes to celebrate his life in only the best ways, personally my goal is to bring his favorite project car to life no matter how hard it is to work on it... Take care and good luck man.
