Ocd fictional character

I'm writing a story about a little girl with ocd. In the first chapter she does not know she has it, what subtypes should be shown and when and where that gets her family a bit concerned.

I never heard about people with OCD who have messy living conditions. Maybe this is why it took so long to accept my diagnosis. Although I really dont like how OCD is percieved at by the majority of people, I feel like Im weird or something because I dont fit into that stereotype. I understand that a lot of people with OCD have this issue, but why do I feel so different? If anybody else has/had this belief, what helps with feeling more comfortable? Everytime my mom points out my room, and how its messy- Its like I feel so lazy and useless. So then I often plan out everything I was going to do, step by step, always having a reasoning behind everything, because logic always comforts me. When I start tidying up my room, I go full out (Sheets, Laundry, Clorox, Candles, Vaccuming, Then I start going through the guinea pigs cage to rearranging all of their stuff) Yet always somewhere after doing a few things, I start feeling disgusting and almost shameful of myself. 99% of the time I end up laying on my floor sobbing, noting every little thing about my room. How my furiniture doesnt match, how i would rather have solid floor like hardwood or vinyl instead of the carpet, usually things i cant change… and then barely anything gets done in my room. I start to have a meltdown and often dont take care of myself even more afterwards. A piece of me feels like my thoughts are just me being a spoiled brat and wanting everything i dont have- meanwhile others dont even have a roof over their head. The other piece of me is just tired, just emotionally exaughsted. Please comment any thoughts or recomendations to maybe improve motovation and attitude towards doing long tasks.

Someone I care about has OCD, he often gets worried to answer certain things in fear that he might be wrong or gets anxious in times when certain conversations such as dealing with negative emotions come into play and in the event something goes wrong even though we deal with the issue it takes him a long time to put himself back together. Often times worried about his image, hyper focused on being a good person etc etc. I believe I’m doing my best but as someone who doesn’t struggle with OCD I cant fully comprehend him and i wish to learn more about it, not just read it off of google. Any advice would be appreciate it. -Thank you!
