just my opinion but it sounds to me as if you have a lot of bottled up emotion

do you switch so rapidly because you keep it all inside, the second a worrying situation comes up you become extremely worried because you have suppressed all this other worry, does that make sense?

Maybe try writing out emotions such as worry, or taking up something physical, e.g. walking, running, swimming, boxing....for your anger issues. Do you make time for just your self? An hour a day most people should, even if it is just a quiet bath and reading, you should always make sure you look after your self. Thats the advice I've always been given by my T's any way.

As for seeing things, this could be from anxiety, which gives you paranoia, but it is deffinatly advisable to see a psychiatrist if you are not already.
