Sorry that you're going through something OP. Everything I say after this is probably something you don't want to hear, so read on at your peril.

The reason people tell you to go to your doctor when you ask for medical advice online is because the question itself implies you want good or useful advice and nobody besides you're medical team can give you that. You can find some general stuff online or ask to speak to a different doctor if there's trust issues with your current provider, but nobody without access to your personal medical history is able to advise you accurately. It takes at least 8 years of constant study to be a newbie doctor. Human bodies are extremely complex, and we still don't know how everything works. Even if we did, not all bodies work the same way. On top of that, humans are shit at statistics, and we heavily bias anecdotal evidence, especially when it is our own anecdote or from someone we know.

Here's a simple example.

Say I get an upset stomach after eating meals and I complain about it to a friend. Trying to be helpful, they told me they used to get that too, so they tried switching to a vegetarian diet, and they got better. Sounds innocent enough, right? I know what vegetarian means (it's "common sense", right?) so I stop eating meat and start getting salads or fruit for lunch instead. After about a week, I fell asleep while driving home. Turns out, I'm anemic. I was getting just enough iron on my old diet to keep the worst symptoms that would have scared me enough to see a doctor at bay, but when I cut out meat I went from iron deficient to anemic. Had I gone to the doctor, they'd have easily seen my iron deficiency and put me on a supplement or advised me how to change my diet, and the nausea would have gone away. Instead, I end up imaking my condition worse and landing in the ER after an auto crash.

That didn't actually happen, but I think it's a good example for several reasons. It's a common side effect (nausea) of a common problem (iron deficiency) that you're likely to think doesn't warrant a doctor, but you'd still mention to a friend. It's a super common symptom associated with lots of conditions. The friend even gave good advice (for most people, changing their diet wouldn't have been an issue, but because of an underlying medical condition specific to our protagonist, it was bad advice FOR THEM). The friend had no way of knowing or even suspecting it could be dangerous advice because most people don't spend a decade learning about the body and disease more generally and they didn't know about the specific issues related to the specific case. It's the same reason you shouldn't get legal advice online... It's a super complex system, and every case is literally different.
