This is my story and I need help

So I'm in tenth grade. I'm still in the closet but I know I'm gay. I recently just moved to a new school last year and have no friends. Sure when I got situated I tried getting a boyfriend but, there was only lume three others like me and they all were seniors, so I felt alone. Then this year a boy told me he was Bisexual and I got his number. So the bext day I invited him over my house to just watch American Horror Story, but half way through he moved closer to me and cuddled up against me it was magical. Then he kissed me. It was my first kiss and it was amazing. We made put for about thirty minutes and he told me he wanted to go all the way but I wanted to wait so he agreed. Then the next day I texted him first thin I got to school. He didn't respond. Now mind tou the night before he had told me his parents were homophobic and we couldn't be together in the public. That I was fine with since I wasn't ready to come out either, so we decided to keep it a secret. So today when I texted him this morning he didn't respond. I was flabbergasted, I thought for sure he like me he even said so, so I just thought he had it on silent an hour later I text him again hoping he'd answer, then nothing. Two hours later I texted him again but gave up after that until after school. After that I called him and he picked up so I was pleasantly suprised, and I asked him why didn't you answer? He tells me he was "at the dentist" and that his phone was dead this I believed, and it made me happier to know he wasn't ignoring me. This raised my spirits because all day of him not texting me back made me feel sick to my stomach thinking about the fact he didn't like me. So I was very happy until tonight when I texted him and he told me he was STRAIGHT. I mean I'm not trying to be selfish and I respect is decision but I don't buy it. He was hard when we were making out so I just don't know what to do. I have no friends, no one to talk to who will understand what I'm going through. Its not like I'm older and can just use dating apps, it doesn't work that way. Please give me some repsonses I'm probably just being over dramatic but I have nothing in my life and I feel so empty inside like I'm goign to puke.
