I’ve noticed that a lot of my friends who have psychiatric diagnoses display at least minor symptoms of other conditions as well. Depression with a side of Tourette’s. Bipolar with a soupçon of OCD. OCD with a smidge of anxiety disorder. PTSD with all of the above.
The symptoms of the secondary problem are usually not severe enough to warrant a second diagnosis and a separate treatment regimen. Most likely the add-ons are noticeable only to the person who has them, or possibly to very close friends (largely those who know about the main condition).
I don’t exclude myself. I have little rituals that help get me through the day, a certain order I do things in. I have a couple of words or phrases I mutter under my breath to keep me centered when I am stressed. (“Kittens” for mild stress and “jumping” for more than that. I suppose that if I ever get into kinky sex, I could use those as my “safe words.”)
Do these mini-disorders ever grow into major ones? I don’t know. They could be coping mechanisms or side effects of medication or fairly routine habits or personality traits.
Mostly I think one should ignore them – until or unless they start causing problems with one’s life. My husband, formerly a certified addiction counselor, says that’s how to tell when drinking or drugs have become a problem – when they start causing problems (in finances, work, relationships, legal matters, etc.)
For now, they’re just little quirks – reminders that my brain has an alternative wiring scheme.
