Day 1 The sentence may not be smooth.

I have experienced brain fog since I was 12 years old.
When the symptoms first started, I thought it was insignificant because it could be overcome to some extent if I came to my senses a little more. Then, when I was 15, I suddenly started to lose sight, and a few minutes later, I suddenly got an extreme headache. At that time, when I searched on the Internet, it was very similar to the symptom of sign migraine, so I took a CT scan at a hospital near my house. However, the doctor told me to just go home because it was just a constitution problem and nothing else was wrong.
But the symptoms didn't end at once. Once a month, the symptoms started to come, and I'm not sure if it was time for stress, but the more stressed I was, the more I felt. I kept getting sick like that, and at the age of 17, because of this, I went to a bigger hospital and got all the tests that I could get, such as MRI, blood tests, electroencephalography, and electroencephalography. However, he said there was no problem. He said he had to be healthier. I kept searching the Internet because I was so frustrated, but I couldn't find a cure, and I just endured such a hard time. At 18, my father recommended me to get manual therapy, and the symptoms of blindness disappeared. At that time, I thought a miracle had happened. However, the symptoms of brain fog, which I couldn't even care about because I was sick, got worse, and seeing myself unable to remember sentences that I could read and remember at once in the past, I thought that the college entrance exam was really ruined. I took the college entrance exam with my brain fog, but the result came out so bad that I was lucky to retake it, and I ended up going to a college that I didn't want to go to, but I was satisfied with some degree. I've had brainfog for too long, and I'm not sure if this is TMS, but there's a case of overcoming brainfog after reading Healing Back Pain, and I got this site recommended.
If brain fog is TMS, my meaning without TMS would be to feel rewarded when I was a kid when I tried to cure this disease, and I appreciate the cured world, and I will do my best not to disappoint those who recognize me. (I'm 25 in Korean age, and I don't live in English, so I want you to know that the sentence is not smooth because I'm on a translator.)
