An endo likely won't help - they'll just look at your TSH and also say it's normal. Endos are trained to look for and treat end stage diseases like Cushing's, Addison's, Thyroid cancer, diabetes, etc. They will rarely treat someone that is borderline hypo even when their symptoms SCREAM hypo.
You really need a good GP that has the sense to understand that TSH is a pituitary hormone, which tells your thyroid to produce thyroid hormone. The theory that a normal TSH means you have normal levels of thyroid hormone is flawed, in particular if you have autoimmune thyroid disease. A conscientious and knowledgable doctor (quite rare actually) will test your Free T3, Free T4 and antibodies: TPO and anti-thyroglobulin antibodies. If you have either of those antibodies, the TSH is totally meaningless. Also, they can do a sonogram of your thyroid and if you have nodules, that also means you have autoimmune thyroid disease and will still benefit from replacement thyroid hormone even if you have normal labs.
I am hypo as are my two sons. My oldest son had perfect labs, my younger son had perfect labs, but he had antibodies. Both sons have lots of nodules visible on a sonogram, so my doctor is treating them so that their TSH nears 1 and their Free T3 and Free T4 are in the midrange. Research shows that by getting the TSH near 1, the nodules can go away (and thus avoid cancer later).
There is a Texas Yahoo Thyroid group (with lots of DFW area members) that is a wealth of info and can provide good info on DFW area docs that will treat your symptoms and not your lab values:

You are so right to not start down the path with the anti-depressants. The long term health impact of untreated hypothyroidism is significant and the impact on quality of life is unacceptable. So, please do keep searching for a doctor that will work with you.
