Welcome to the forum, though your situation sounds frustrating.
It is likely that your difficulties, if related to the vegan diet, can be remedied by a small, appropriate tweak to your eating habits. I say this not because I've been a vegan for 27 years, but because nearly every reputable mainstream health organization and athletic organization has stated that properly-planned vegan diets are healthy. At the end of this posting are links to support this, and links to help you find a local Registered Dietitian.
Regarding hypothyroidism: The Adventist Health Study 2 - one of the largest-ever population studies of vegetarians - found that vegans tend to have a lower incidence of hypothyroidism: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3847753/
. That doesn't mean that vegans can't develop hypothyroidism, of course! However, it does strongly suggest that a properly-planned vegan is unlikely to worsen the likelihood of developing hypothyroidism.
Regarding hypothyroidism and soy foods: Popular health sites and forums are filled with claims about soy foods - from miraculous to terrifying. However, peer-reviewed studies of soy foods are a lot less dramatic. The U.S. National Institutes of Health published this peer-reviewed article about soy foods and thyroid health: http://www.ncbi.nlm.nih.gov/pubmed/16571087
. This article concludes that soy foods are healthy, even for people with hypothyroidism, as long as people consume enough iodine in their diets.
Regarding joint health: The Arthritis Foundation has stated that vegetarian/vegan diets tend either to have no effect on joint health/swelling, or to have a beneficial effect: https://www.arthritis.org/living-wit...rian-diets.php
. Again, this doesn't mean that vegetarians can't get arthritis, but it does suggest that a properly-planned vegetarian diet is likely to be beneficial.
Rather than trying to find nutrition advice from a public forum/podcast, it would be better/safer to consult with a Registered Dietitian who specializes in vegetarian diets.
