Bri, don't you even talk about giving up, I know you are worth more than that. They gave me one of those career aptitude tests in high school once and the school counselor said the only thing I qualified for was a watch maker!!! Now where in the world did a category like that get into a testing guide for the United States!? When I went into Real Estate I had to take a whole battery of personality and aptitude tests all over again and I actually recognized some of the questions. When the guy reviewed the scores with me, he laughed and said "This says you should have MY job." I looked at him and said, "You don't think in 40 years I couldn't memorize these answers?" That's what life is, Bri, it's watching the answers go by so many times that one day you will be the only person in the room who has heard them all, and then those teenage snots will have to stand aside and let you through
Something else I thought of that you should definitely do, and that is get a thyroid test. The symptoms you describe are very typical of thyroid or hormone level problems too. Do not ever assume that life doesn't go right because you are somehow inferior, a huge percentage of the time the root of the problem is medical.
