Anyone else have a crazy list of symptoms and no diagnosis?

I’ve been having weird symptoms off and on for the last 5 years, starting when I was drinking way too much green tea. I think all the caffeine set something off, because weird things started happening. I started tripping on my own feet like they were just suddenly heavier. Then I started noticing muscle fatigue more, it was getting worse. I had chest pain, palpitations, and I felt like I couldn’t catch my breath. I was always too hot or too cold, either flushed or my teeth were chattering. My food was not getting digested, it started coming out looking like it did when it went in. I started noticing extreme body odor, and I usually almost never stink. It only took a couple of minutes to stink again after washing. I quit drinking caffeine but I still felt terrible. My coworkers were concerned and my employer paid for me to go to the doctor (I don’t have health insurance), but after telling him my symptoms, he just said “huh”. He said some of the symptoms sounded like thyroid, so he ordered the regular panel of blood tests plus a thyroid marker. I got a robocall saying that all of my tests came back within the normal range. But I felt like I was definitely dying, and like my doctor didn’t care. So I went to Dr. Google, because he’s free, and found the auto-immune reset diet. It was insanely hard but I started feeling better after only a week or two. After a month I started eating regular food again and I was almost completely better. Since then, I will be fine for months, then start having symptoms again and have to go on the diet. It’s terrible, but I’ve grown very fond of roasted vegetables. I was hoping someone on here had experienced something similar, because I can in no way afford to see a doctor, let alone several specialists who need to run every single test. The diet is working for me for now, but it would be really nice to know I’m not crazy.
