so tired of not knowing whether i have ocd or not, it's driving me crazy

Ok, so first of all, I’m undiagnosed. However, I’ve been pretty certain for a while now that what I’ve been struggling with is OCD. My problem though is that it’s not easy to get diagnosed, and in some cases, it would require me to pay money. It frustrates me that I have to pay to deal with my mental health. Is it worth it for me to get diagnosed? I know I don’t need a diagnosis to start healing and working on these things, but I also don’t want to be “self diagnosing” the problem, because that makes me feel like a liar and an imposter. My other problem is that I fear my family doctor won’t properly diagnose me. I came to him about mental health related issues once before, and he read off a very generic list of mental health symptoms. when he got to what sounded like the ‘OCD’ section, we asked one or two very generic questions that had nothing to do with my themes, and since I couldn’t relate, I just answered no to them. He then told me I was fine, that I was just a “type A personality”, and that I was just being too hard on myself. I fear that my doctor might not be very knowledgeable or up to date on current information regarding OCD, and this might make it increasingly difficult for me to get diagnosed. Another problem is my symptoms seem to come and go. I often have an obsessive cycle that can last months at a time, and then it just goes away. Sometimes I won’t experience any symptoms for years. This makes me feel like I don’t actually have OCD or that it’s not ‘bad’ enough to be diagnosable.

I used to be able to determine what was my OCD and what’s real life but now it’s all just blending together. I literally can’t tell what’s true between what’s not true. my overthinking is absolutely terrible and rituals and everything is just crumbling.

Why does ocd make you feel uncertain about everything. Even the things you knew were 100% certain before. Its so bizarre. All the subtypes like Rocd, Pocd, Hocd you should be 100% certain about these things but ocd makes you feel like you dont know. I sit here know saying in my head I DONT KNOW. its so hard and confusing. I just want to know who I am. Am I a good person like I thought I was and have been my whole life or am I someone else. I just dont know. Its awful
