These days without you

My friend committed suicide last month, I have not been a happy person since then, she was bi, and made me question my sexuality, what if that was a good thing and I answered my question by saying I'm Bi or Lesbian she could've helped me out but no, this guy came in the girls locker room and sexually harassed her, her parents abused her once they found out about her sexuality, she has had a rough life, and what makes me even more upset is that she says I'm the only one that keeps her alive, so her committing suicide makes me feel like I didn't complete my job of keeping her alive.
