My question for you today is, which type of person are you? Is there a category that you would rather be in than where you are now? The change is most definitely possible, however, going from a toxic person to a bubbly person is a huge jump! If you are toxic and want to change, I suggest working on being a blah person first, then working towards bubbly. Going from toxic to bubbly in a single leap might just overload your system, and scare the heck out of those that know you.
