If you answered yes, to any or all of these questions, it is ok. It doesn't have to be 50/50. Sometimes it can be, but on some days, if not most, the ratios vary.
Keep checking in with yourself, and see how things are working for you, and adjust according to your needs.
No feeling or emotion is forever.
We are not in a constant state of feeling happy, joy, positive, excitement, or enthusiasm. And, it is the same with feeling down, sad, angry or frustrated. These feelings aren't lasting and will eventually subside to new feelings or emotions.
