if i call a kids helpline and tell them that i have obsessive compulsive disorder would they be able to help me or will i end up more confused and disoriented like i am now

I have OCD, but my parents don’t understand what I’m going through. All I wanted was for someone to be by my side and support me, but they dismiss my struggles, telling me to "just stop thinking" and that I’m making a big deal out of nothing. When I asked for a new therapist because my current one isn’t helping—she isn’t even an OCD specialist—they became angry and didn't believe I need therapy and instead blame me for everything. My father was so mad, he insist to gave me a knife and kill myself. He threatened to isolate me completely, cutting me off from school, the internet, and everything else. My mom cried and shut me down when I tried to explain my pain. They refuse to listen and my dad said it’s all my fault. That day they threw me outside the house for a night, and called me back in telling me to forget everything and forgive them, but I understood that I will not be able to mention anything about my mental health or seeing an OCD specialist ever again, I am completely alone now. With no financial support, and now I don’t know if I’ll ever get the proper therapy I need. I’m only 15, but it feels like I’ll be trapped in this suffering forever, I feel hopeless, I feel like shit, I am going to suffer forever with no support and help.

Sometimes I think " do I like kids?" "Would i get aroused if I saw content with kids?""What if I'm a pedo and cant accept it?" "What if I'm ok with these thoughts?" "What if I'm not distressed enough " "What if I enjoy these thoughts?" , i avoid kids as much as i can, i cant look at them bc I'm scared I'm gonna have some groin like response. I keep testing if I'd get turned on or if I'd have some groinal response to sexual scenarios with kids. Sometimes I think that if I took my life this would be over and i wouldn't have to think about this and i wish i doubted something else instead of things like this. I had similar situations just with different topics such as if i loved or found sexually appealing a guy while in a relationship and i kept asking myself those questions for months and i avoided going to school for weeks and when I went I'd cry and have anxiety attacks. I had it with past actions i obessed over and felt the need to exploit every detail and be honest because otherwise i was being a fraud. I had it for sexual things that happened when i was a child. Im not diagnosed with ocd but should i tell this to my local counselor? Can someone help? Give me advice or tell me anything?

I'm 15 turning 16 soon and I'm 100 percent convinced I have ocd.. I have been having major symptoms since I was 13, the constant what ifs, rumination, compulsions, guilt, anxiety from intrusive thoughts. I tried to open up about it to my parents when i was 13 but they dismissed it cause they don't believe in mental health.. I really want to get better. My parents won't listen to me and I don't wanna tell a teacher at school cause that would make things worse as they would just tell my parents and obviously since I'm 15 I can't afford therapy.. I don't know what to do :(
