I get a bunch of mood swings. Sometimes I can be euphoric and then a few minutes later I can feel guilty about something that happened two years ago. This goes on constantly throughout the day. But the werid thing, is that I hardly ever show these mood swings. They are only in my head. They are so private, that I have been told I do not have a mood disorder. I appear to be very stable. I'm not saying I'm not stable, I'm actually doing very well. I can snap out of these mood swings quickly by using mindfulness and distractions, but they always come back. I can have mood swings several times an hour, but I hardly ever show any type of mood swings. I actually appear to be dull and affectionless. I usually just keep to myself and am quiet. Yet I am very competitive, slightly conceited, and often judgmental. I do have severe PMDD, and I am a completely different person in a bad way when I am PMSing. But In general, I seem emotionless. Does anyone know why I have so many mood swings but don't vocalize them? I've never heard of any other cases. Maybe I just have good control over them?
