Find a good endocrinologist. They will listen to your symptoms and adjust based on them along with all of your thyroid test, and they should be testing tsh, t4, .and t3. All are important.
Your TSH could be high for you. Even at 4.0 you could be hyperthyroid and you could be hypothyroid... A lot of the symptoms crossover with each other. But they all definitely sound like a thyroid disorder. I have hashimoto's thyroiditis myself. It's really complicated, and even a lot of endocrinologists mistreat it.
