My question is, is it possible to have Cyclothymic Disorder if I have no family history of mental illness? I've recently been researching Bipolar Disorder and Cyclothymia, and I've come to realize that I have many of the Cyclothymic symptoms, but neither side of my family have had any form of mental illness, so there's nowhere genetically that this could stem from, but I'm very confident in my self-diagnosis to the point where I'm afraid I might have to get it professionally diagnosed to make sure. Any answers are greatly appreciated. This question is making me incredibly anxious.
