Help idk what to do anymore

Help idk what to do anymore. I just turned 14 on the 23 , I have depression. & I cut tonight & I'm scared. My sister, & best friends know that I have thoughts of killing myself & of cutting. But tonight I acted on my thoughts. I don't want to be in a hospital cause school doesn't start till the 5th. What if I try to kill myself, I'm scared as shit. What should I do I don't want my mom cause she'll send me away & I can't handle that.😔😞 Please help me. One of my best friends already know & she's pissed at me now.😞
