Although I am fortunate because I can say that nothing like this has ever happened to me, my sincerest, warmest condolences go out to you and your roommate's friends and family. I cannot imagine what it must be like. I hope you find strength and light in a time of darkness.

I wish you the very best of luck on both your last year of college and your startup; enjoy them as much as possible!
