Im A Lesbian my brother is gay and my best friend is bisexual

So here is how the bullying started

Me and my best friend went out to chick-fil-a and i was planning on telling her i Was a lesbian so thats what i did put what i didnt expect is one of my classmates (the gossip girl) to be there i didnt notice her until i told my bestfriend i was A Lesbian i guess the girl heard me say i was a lesbian and told the whole school long story short people start telling me im a horrible person that i deserve to go to hell that im not a Christian that i am one of satans creations and to be honest those words really hurt me so everyday ive gone home and cut and ive been clean for 2 hours but i know i will never go a day clean maybe because ill be dead maybe just maybe
