I did something bad and I'm so scared!

I'm.scared I'm gonna get in trouble.... My best friend got me into a mess! Her boyfriend of 4 months broke up with her.... She has suspected he was gay because she found gay porn on his phone and she MADE me make a fake Facebook to try and figure it out. We made it and we were.talking to him as a hot guy. He was obviously flirting which pissed my friend off. We kept this going and it go sexual. We would get online to find dick pics to send him while he sent us his and his dick wasn't all that big. I think he started catching feelings for our fake person because he started opening up about some dark stuff from his past. We were all having fun. After a month and a half of this my friend said we should post this on Facebook.... So we screenshot everything, posted it on Facebook, and blocked him on messenger so he can still see it.... Everything was on there.. We tagged.him and said #Exposed. A couple days later we get a message request from his sister that said "Casey, Alyssa. I know its you. I'm gonna beat your asses. My brother tried to kill himself! His mom called my mom and they are getting POLICE involved.. What's gonna happen to me..

Edit: My mom isn't gonna get me a lawyer... She is so mad at me because she lost her brother to suicide and said whatever punishment I get I deserve.

Edit: Okay everyone saying how horrible I am. This wasn't my idea. I didn't come up with this shit. My best friend did. I sure as hell didn't tell anyone to kill themselves. Also we didn't distribute child porn. He's 16 and that's legal age of consent here. None of this was my idea yet I'm getting in trouble. I went along with this because that's what best friends do. If he was gay maybe he shouldn't be dating girls! I'm being called a bully and other shit and I do not care anymore. In a year none of this b.s will matter. I have 1 more year until college and I'm not letting this situation fuck up my plans. If my mom doesn't want to get me a lawyer like someone said court will get me one. But this is stupid because this wasn't even my fucking idea!
