You CAN and will, if you choose to. One specific thing that helps me a lot is positive suggestion statements. These are not "affirmations," per se - but I suppose a similar concept. A few of mine, that were written in concert with a trained pro - "You are worthy." "You have value." "You engage in activities that are joyful and creative." Knowing what I know now, I am able to craft my own statements now. I write them out once a day, listen to a recorded version of them a few times a week, and think of them sometimes throughout the course of the day. It helps to train your brain to get on a more positive track. Focusing on gratitude and helping others are also helpful. Best!
