Huh? That link is to an abstract of a paper that says, in entirety:

Bisexual people experience monosexism, the privileging of sexual attraction to one sex or gender, from heterosexual, gay, and lesbian communities. The current study of 745 bisexual-identified participants explored their experiences of monosexism with heterosexual family members, heterosexual friends, gay family members, and gay friends. Results indicated that bisexual individuals reported significantly more discrimination from the heterosexual community in comparison to the gay or lesbian community, although the effect size was small. Acceptance of bisexuality from family and acceptance of bisexuality from friends were negative predictors of antibisexual discrimination. Clinical and research implications are discussed.

The abstract mentions neither "distress" nor "attempted suicide" amongst bisexual people. In your post that I challenged, you said bisexuals have "high rates of distress" and claimed that "an Australian study" showed that 28% of bisexual people have attempted suicide.

As a mostly het but occasionally same-sex attracted person, I have no doubt that bisexual people experience discrimination and exclusion. But we shouldn't conclude from this fact that as a result bi people suffer "high rates of distress" and attempt suicide at unusual rates (28%).
