Frustrated!!

So, I am really frustrated! I am feeling like I am stuck at my weight. I work out pretty much everyday, I mix up my workouts, I have been trying to eat healthy and I am losing no weight. Mom even suggested that maybe I need to eat more, so I have been eating smaller more frequent meals and still, nothing. Then, I began researching thyroid issues. Now, that I know that I have inherited those issues on both genetic sides and I am fitting some of the symptoms, I am making an appointment with the doctor to get it tested. I just feel so sluggish all the time, even when I have had plenty of sleep and exercise is supposed to energize, not deplete you!
