Kurt Cobain was troubled long before he committed suicide. It started even earlier, when he questioned his identity as an adolescent and wondered whether he might be gay. He said he had a gay friend when he was growing up, but his mom banned him from hanging out with him, so Kurt never had the chance to experiment with it.
This revelation is from an interview Kurt did in 1993. The comments about possibly being gay start at 2:50. (
