Having a severely depressed brother

I can’t help but slightly blame my family for my lack of mental health. I have a mother that is a good person but cares so much about appearances that I now have anxiety over any imperfections. My dad yelled at me and my brother so much that my first reaction to anything is anger. And my dad literally always talks about how amazing my brother is. I was telling him how my boyfriend helped me out a lot by teaching me how to study and he then proceeded to name how much smarter my brother is. None of this pertains to OCD necessarily but it caused me to spiral. Usually that means cleaning but my house is cleaning so I’m just obsessing over how literally everyone but my mother thinks my brother is better. I love him very much. But part of me thinks that if he wasn’t here, my life would be better. My Pure O is more of the problem than OCD. There are no compulsions. Just obsessed with the idea that my brother will always be better than me. No matter what. It’s stupid but I just want to be a priority to someone other than my boyfriend or Jesus. I want someone in my family to understand my struggle with various mental illnesses and with always coming in second to my brother.

Just got my OCD diagnosis last week. In trying to tell my brother, he shrugs it off as "everyone has OCD" to a certain extent. Seriously can't talk to someone who won't even try to understand.

So I’ve recently discovered my ocd, my brother had been diagnosed when he was younger and struggles to a lot more noticeable degree. My parents have tried to their knowledge to help him with his obsessions before he had started therapy. I’ve always been there for my brother when he’s really dwelling on a trigger. Over time I had learned more and more about ocd and started to discover things about myself I never understood. I have struggled with mental health since I can remember and always brushed it off as chronic paranoia. But I started notice a lot of similarities between mine and my brothers triggers and after researching, realized I too suffer ocd obsessions and compulsions. My huge concern right now is even though my triggers and obsessions are different than his, I feel doubt about whether it not I am valid to speak on it. I feel guilty because I have watched him suffer false memory ocd and I don’t experience that so to me it seems ultimately worse. I had opened up to him recently about things I’ve been struggling with since I was little and he confirmed all of it as ocd thoughts and obsessions. I feel like suddenly all these unanswered questions about what’s wrong with me suddenly makes sense, but I’m so behind in discovering this that I’m afraid of being honest about it, and it being perceived by others as me trying to combat with my brothers experiences. I can talk to a therapist and it’ll feel like I’m being seen, but in my personal life, even with my boyfriend I have the chronic fear that people think I’m lying
