That must have been really hard to be misdiagnosed for so many years. I thought for many years I had MDD/GAD, and it was finally confirmed by my psychiatrist, but turns out I had bipolar and now we think OCD. So I was misdiagnosed for a little less than a year. Even after the bipolar diagnosis I felt like something else was going on and it did not click until I learned more about OCD. I kind of feel some regret for not seeking help sooner, because I really got worse instead of better over time.
