If I were you, I would elaborate more on the actual sentence and the words you use in it, instead of just sticking to these. "I've always been an emotional person who experienced the world through a myriad of emotions" - I am sure it's not what you are trying to say, but just get your thoughts in that direction.

Are you trying to say that someone who has strong emotions or something else?

"A person who has deep thoughts and feelings" is an emotional person or a temperamental.

both sound right for me;)
