My mood tends to be all over the place as well. I see a psychiatrist and am on meds. Have you thought of that or therapy? I have limited people in my life but even when I am around others I feel alone. There is an inner sense of sadness,confusion,fear. I try to find ways to comfort myself within. In terms of people understanding in life some will to a degree and some will never. So I try to focus on the ones that try. I reach out for support in ways I can and try to find ways to cope with myself. Hang in there
