Help!!! Do I have a thyroid problem????

I have always had issues with anxiety, depression, heat intolerance, blushing and nervousness. I always attributed these things to the abusive childhood I had. However, during my pregnancy all of these symptoms got even worse. I went back on Lexapro after my daughter was born but I am still struggling with a lot of these symptoms 18 months later only now I am also having trouble losing weight. The biggest issue for me is the heat issue. I am always warm when others are actually freezing. When I feel hot my anxiety goes through the roof and my face gets very flushed. I have seen various endocronologists and have been told that my thyroid levels are "normal". I have tried to lose weight since I had my daughter but it is so hard. I have been told that I have adrenal fatigue but can't that also affect the thyroid or vice versa? So, here I am with symptoms of both hypothyroidism and hyperthyroidism and no doctor to help me. I have read that many blood tests come back "normal" and so many women go undiagnosed. So where does one turn when that is the case??
