I Currently Suffer From Anxiety And Depression....both At Same Time

I currently suffer from anxiety and depression....both at same time and have for years, with times in my life where I was without a lot of symptoms, and very manageable. I don’t think I have manic episodes, but I have days if I slept well, I have a bunch of energy and creativity. They say that bipolar 2 have manic episodes where they require little sleep. I have insomnia, but CRAVE sleep, and am anxious and depressed when I don’t get enough sleep because of stress and worry. I’ve sought the help of therapists for years. Is there any chance I could be bipolar 2, or just prone to anxiety/depression?
