Your hormone levels indicate hyperthyroidism, not hypothyroidism, but you could have Hashimoto's; you could also have Graves Disease, although you can't know that from these results. Hashimoto's and Graves are autoimmune conditions and in order to find out if you have either (or both), you have to have the right antibody tests.
Although Hashimoto's is known to be associated with hypothyroidism, early stages can be characterized by stages of hyperthyroidism, alternating with hypo or even normal periods.
To determine if you have Hashimoto's, you need antibody tests, Thyroid Peroxidase Antibodies (TPOab) and Thyroglobulin Antibodies (TgAb). The definitive test for Graves Disease is Thyroid Stimulating Immunoglobulin (TSI).
It would be a good idea to have Vitamin B12, Vitamin D and Ferritin tested. Many vegetarians are deficient in vitamin B12 because its main source is animal sources such as meat, dairy, eggs, etc. Plant sources of B12 are extremely difficult to absorb. Vegetarians/vegans usually have to supplement B12 in order to maintain adequate levels. B12 deficiency can cause symptoms you describe, though it won't typically affect weight. Vitamin D is necessary for proper metabolism of thyroid hormones, as is Ferritin, which is the iron storage hormone, so it would be a good idea to go ahead and get a complete iron panel, as well.
Many of these tests can be ordered online, without a doctor's order, at far less expensive rates. If you're interested, we can tell you how to do that.
I've had both types of Hashitoxicosis. I have Hashimoto's thyroiditis but my labs were weird lol when Graves antibodies showed up as well. My labs showed subclinical hypothyroidism with only the TSH slightly above the range at 6 and I was very hyperthyroid. I read a blog entitled Hashitoxicosis: Does It Really Exist? YES and here is an excerpt..
"Here's what stumps doctors most when you are dealing with Hashitoxicosis - your labs. Due to this constant cycling of hypo to hyper from minute to minute and hour to hour, the net effect of these changes is a zero sum game - normal labs."
The leakage hyperthyroid symptoms of active Hashimoto's thyroiditis are milder symptoms compared to Graves. My symptoms of Graves also caused pretibal myxedema and eye symptoms such as red eyes and light sensitivity.
"It should be pointed out that, especially in the US literature, the term ‘hashitoxicosis’ is sometimes used to describe an autoimmune thyroid disease overlap syndrome of Graves’ and Hashimoto’s disease.2 In this article the term is strictly limited to the ‘leakage’ symptoms of active Hashimoto’s disease.
Hashitoxicosis is most likely to present in the early stages of autoimmune hypothyroidism."

Hashitoxicosis – Three Cases and a Review of the Literature
Looks hyper to me. I felt horrible when my FT4 was high. Could be Hashimotos, Graves, neither or both. Your doctor should check your antibodies (TSI for graves, TPO and TG for Hashimotos). You could try asking your PCP to run these tests and explaining that your insurance doesn't cover an endocrinologist. You may want to double check with your insurance, I've never heard of a plan that doesn't cover endocrinologists.
You probably want to ask them to check your FT3 levels too.
You need to insist on having the antibody tests I mentioned above in order to determine exactly what you have... without them, you can't tell for sure what condition(s) you actually have.
It's good that you've been referred to an endo, but remember, not all endos are good thyroid doctors as many actually specialize in diabetes rather than thyroid. Be sure to advocate in your own behalf.
