Emotions

One of the great things about the Disney movie Inside Out was how it showed the emotions Riley experienced clearly and how that impacted on her attitude and behaviour clearly identifying them
Identifying our emotions is actually quite hard for some of us which does lead into other problem areas such as being able to tell people how we feel and also regulate them as it's as if you have two states, full on or squashed.

Actually although this chart was done for the movie, it is surprisingly helpful for those of who have these problems because you can easily tell where the overlapping of base emotions  lead  as they are clearly labelled so you can better thing through for yourself what you're feeling and communicate it to significant people in your life so they understand what you're feeling being better able to guide you managing the resulting emotions and behaviour you exhibit.
Learning to manage them is important.
