Coming out to my parents was the worst out of all !y coming out expirences. I got nervous, as a lot of people do, and started crying. My parents thought I was crying because I was sorry for liking guys. Then they told me it was just a phase and everyone thinks they're bisexual at one point in their life and that bisexuality doesn't even exist
I have friends well into their 30s and they're still bi. The fact is possibly a majority of people are bi - but most cluster so close to one end of the spectrum or the other (gay or straight), that they just go with those. Myself included. I'm really sorry you had such an awful coming out experience. How accepting were they? Obviously not do much in believing of what your sexuality is, but are they still supportive? If you need a hug we're here for you.
