I have OCD and generalized anxiety. I am far from a slob, but you would never look at my apartment and think, "wow, this certainly smells like OCD!" I have a few dishes in the sink at any given moment, my bookshelf is only loosely arranged by size and theme, and my workspace looks like a workspace, not an IKEA showroom (actually, on second thought, it does because everything's from IKEA). I understand that these stereotypes come from pop-culture depictions, and that can be simultaneously frustrating and kind of a relief. Frustrating because people tend to doubt that I actually have it because I don't present according to the popular image, but also a relief because, although often depicted wrongly in pop-culture, the pop-culture prevalence has removed some of the stigma of OCD compared to other mental disorders. I don't talk about it often, but when circumstances necessitate, it makes it easier to bring it up because it's something that everyone has at least some idea about. Another downside, though, is that because of the pop-culture treatment of OCD, people tend to think of it as a funny quirk and something superficial or harmless rather than something that causes serious problems.

As for generalized anxiety, the only thing I wish I could get across to people is that telling me not to stress and to just relax does absolutely nothing. Sometimes this advice is intended to comfort and to relieve the anxiety, and other times it comes from a place of irritation from people who have had it with my catastrophising.

And another thing that ties into my experiences with both conditions: when I seem functional and capable and high-achieving or whatever, that's because I am, but as long as I have some degree of control over my environment. If I seem nervous or stressed out or anxious or distracted and would rather just be left alone to collect myself, it's not because I don't want your company or whatever, it's because I need to regroup my shit to get back to a functional level. It's doable, it just takes me longer to do it and I do it more frequently and with more effort.
