I’m scared to ask for help! 😭😭😭

I have currently been sitting in the bathroom for 3 and a half hours crying because I didn’t know what else to do!!! One of my old teachers started acting very weird when I turned 18 and I transferred out of that class but we had an early release today and so I just went straight to my apartment. He knocked on the door after our track meet and I stood there staring and was obviously uncomfortable but he asked to come in and I wasn’t thinking, long story short he started getting closer to me and when I said I was uncomfortable he grabbed my arms and shoved me down on the couch and rapped me!!! I tried to push him but he’s bigger then me, once he came in me he grabbed my mouth and said if I ever told anyone he would do it again!!! I’m so scared someone please tell me what to do!!! 😭😭😭😭
