Im having trouble forming opinions and correct decisions, idk who and what to believe regarding any theory or beliefs. Idk whats right and whats wrong. Shit is depressing me so hard. Any advice on what to do?

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 feel like im no longer living im only 17 and i use to be so excited to turn 18 recently i feel like life is pointless and its all i think about including philosophy and i never liked that before. It has taken complete joy out of my life anything simple like watching a movie feels pointless because it has no meaning and i feel as if my life has zero meaning because i am not important. I am constantly criticizing everything. For example i went to a concert ive been dying to see and when i got there i didnt enjoy it all because i felt like it was pointless. Is there anyone that has experienced this that has advice I feel like im in hell rn

I think when people are saying OCD is egodystonic is really triggering me and I was just wondering if this has happened to anyone else? I’m going through a really bad relapse and right now I’m trying to figure out if my thoughts are truly egodystonic, like I how do I know I won’t act on them, how can I trust my emotions and everything. I feel really confused and I feel like I don’t know who I am anymore or how I carry on with life because it’s so long and I’m so unsure of everything that’s going on in my head. Like how do I know that this is OCD and true desires/urges. I’m so confused.
