Yes, I do consider myself mentally ill. I see it like any other chronic illness, mental or physical. Something has changed within me and I no longer function "normally," in such a way that it can and does affect my quality of life when not controlled. Like some other chronic illnesses, it also causes additional problems (severe anxiety, long periods of depression, irritable bowel syndrome). Also like many chronic conditions, it's invisible. It's not an injury that people can see and immediately understand. I also believe that mine is so invasive and persistent because I'm genetically predisposed to mood disorders, as they're quite prevelant on my mother's side of the family.
I believe I can continue to heal, that I'll eventually experience fewer, less intrusive symptoms, but I don't think I'll ever be "cured." I firmly believe that this is permanent, and that my focus should be on managing and understanding it rather than hoping for it to eventually be taken away from me.
Right now my greatest worry about my illness is how it will affect my future children, me as a parent, and my husband as a parent and partner, as this is all coming up quite soon.
