Hi Breezy. It's easy to get into a pattern of unhappy thoughts. I have a problem with this myself. And I've found once I let it start, it does not stop without extreme force of willpower. It helps to make a conscious effort to not dwell on such things. I choose a phrase to say to myself when I find my mind wandering that way. Right now it's "Stop thinking like that!". It won't cure your ills, but it helps in the moment. Try to replace negative with positive. Do go to a therapist, they help you discover more about yourself and why you are the way you are.
