When my boy 18 years old, I met an online fortune teller and said that my IQ was very strange. Speaking of my heart, I also feel that my IQ is very strange.

I think you like thinking very much. The fact that you doubt your IQ is a question of thinking. You must often think about your IQ, but in fact, how can people with low IQ doubt their IQ? Maybe it's because of my poor performance in mental work, and I feel that my IQ is not high. But in fact, many great scientists did not perform well in school and even dropped out. Comparing with other people's IQ is not based on scores and performance. Instead of doubting your IQ, try to change this situation. Asking for help from others is your first step. Everyone will have their own expertise and interests. It is definitely a good choice to develop yourself.

If it is because of the lack of mental exercise and knowledge accumulation in the past, it is not too late to change it now. Illiterates in the new era are not illiterate and can't calculate math problems, but unwilling to learn and not paying attention to learning. If you attach so much importance to your IQ, you will certainly succeed in changing the status quo.
