Sometimes I feel too old for OCD

I've been struggling with ocd since I was 7. I'm 18 now and it feels like the older I've gotten the worse it's gotten. I don't know how to deal with it and i feel so lost and alone. Its hard for me to even say what my intrusive thoughts are or to even fully acknowledge it to myself in my head because im scared that if i put it out in the world itll be true or if i acknowledge the thought it solidifies it and makes it true. i feel like im just over exaggerating what im feeling and im turning something that isnt there into something bigger which makes it hard to talk about it with other people. Especially because im not diagnosed but I know it's ocd but what if it isnt? What if im lying to myself or I'm just doing it to get attention and I don't realize it? I just try to deal with it on my own but it's so hard and feels impossible. I feel like ocd has contaminated every part of my life that I enjoy. The things that used to bring me comfort are now filled with things that trigger my ocd and bring me anxiety.

Not sure what to say. Just that I am so tired of dealing with OCD - I’ve had it for most of my life and as a 40 something woman, I’m exhausted. I’m tired of being misunderstood and mistreated. I’m tired of seeing relationships that I have dwindle bc my friends and family are overwhelmed with my ruminations and reassurance. I’m embarrassed bc I overwhelm my friends and family with whom I’ve trusted my personal thoughts with and I keep thinking that they can help me through stuff only to be let down. I’ve yet to meet another mind like mines who is complicated but trying to survive because I have children and want to see them grow. I’m tired of feeling defeated because someone took advantage of me and my thoughts. It’s so exhausting but I’m ready to try this because I know I need help. Not sure if this is triggering I’m just ranting bc I’m so lost.

I was diagnosed with OCD around the age of 6, subtype- contamination primarily. It calmed down as I got older and I assumed it had gone away, but also didn’t realize it can show up in other ways, and it still had been effecting me which I know now. I’m not 31 and I’ve been in therapy for a year and it’s helped a lot, although I sometimes get thoughts that what if some of the stuff I’m dealing with isn’t ocd and I’m exaggerating. I feel like thoughts will feel sticky and I’ll do certain compulsions but then the thought eventually vanishes if I do it a few times which makes me think maybe it’s not OCD since other people/friends I know would probably do the exact same thing. Not sure if I’m making sense, but I guess my question is if that thought comes up with anyone else? Just being unsure if something you’re doing actually is ocd or not.
