Trying to get diagnosed

Im a teenager and i think i have ocd. I recentley went to a phyciatrist to try and get diagnosed. I already struggle beliving i have it because for some reason my brain tells me that i dont actually have it and am just looking for attention. Ive been doing so much research and ocd fits all my thoughts and patterns. Anyways, i told her my concern and she asked if i had chronic hand washing and if i get bothered by clothing material. Thats it. And then she said she doesnt think its ocd and its just anxiety. Should i keep trying? Is it normal for ocd to be hard to diagnose or for people to not believe you? Idk what to do. I just built the confidence to get help and i feel lost. Any tips or advice is appreciated.
