I can just assume you feel you lost IQ points through mental illness. Yes that happens. When you're mentally ill, your brain doesn't work as well, it sort of goes without saying.

106 is not low, it is high normal. My cousin is a steady 110 and she went out in the world to make a difference. Very smart and compassionate person. So I really don't want to hear how 106 cannot bring you anywhere.

When I was really depressed I scored lower than normal on IQ tests. But after I got better, guess what? I scored well again! I bet if you take an IQ test while having flu it wouldn't go well either.

Work on your mental health and your self esteem and your IQ will come back up.

120 is not average, it is high. I've never met anyone who has 150, my brother has 140 and he is the smartest person I know.

Also people of low IQ can work really well in some areas, I used to work with a 15 year old kid who scored at 65 and he was one of the nicest and best workers at that workplace. He couldn't write well either but it wasn't part of his job.
