Yes, as a person with Bipolar II I often ghost friends and family. I do this because I do not want them to be subjected to the severe effects of suffering I go through. Some of which include, crying many times a day, unable to control my emotions well, irritability and rudeness, and even the changes to the way I think. I don't believe I am in my right mind in a severe low, and even the moderate highs I get from hypomania. Contrary to what many may think, if a family member or friend sticks with you through these periods of time, they will suffer from being around you and seeing you act this way, and the way you think, and though you may not lash out at them, it is a struggle not to sometimes and it is much easier to cut them off until I am more stable. In short. I have no desire to hurt others and cause them any sort of suffering, and my depressive episodes can last weeks. Better to push them away for that time until I can think clearly. I do agree that communication is very helpful to those you love when you need to be alone because you are suffering, send that text first.
