If there is someone, a family member or significant other that you trust, be sure to tell them how you are feeling. When you are in a dark place, it's easy to get tunnel vision. They may not be able to "fix it" the way a professional can, but they may be able to help you along and give you the perspective you need.
There is a book "Change Your Brain, Change Your Life" which has been great for me and my husband. Basically, you find out which profile fits you, and then it gives you specific advice for how to improve yourself. When I was reading my own profile, and that of my husbands, I was like yes, yes that's it! It was like it was describing us personally. And we had already learned through self-study some of the benefits that helped us. But once we saw them reinforced, we know to do them more consciously.
