POll: bisexual divorcee dad got me pregnant?

He came out as bi, and my grandma freaked out. Theyve been together for a yeat now. Shes torn apart. Ive tried to comfort her, but sje says not only has he been with her, ge dated a middle schooler eight months after he broke up with me. The worst part us, now my grandma feels betrayed and im pregnant with my dads baby. Im only 15 what can i do? My dads gone, my mom is now single, my grandma has no one to **** and is suicidal, and im pregnant. Also my cat lloyd died. What now?
