Thank you both for your input. SadHub, you're absolutely correct. In the beginning, I would just find distractions to fight those thoughts, I quickly learned that was not the way to handle it. It's definitely best to acknowledge the thoughts and move forward from there, I just haven't become very good at that yet. Many times the thoughts bring me down, but I'm sure with time, that will get better.
I'll check out the Ted Talk you recommended. Thanks for suggesting it!
