I'm going to say you are a special flower. You're smarter than 98% of people. You are 1 in 50 special.
I think from your own words you would have benefited greatly from gifted education. Thinking about your story here, I think that maybe lowering the IQ bar to something like 125 is exactly what gifted education needs.
Look at what you said:
"I could cope with everything and everyone if I tried even a little."
You were coping, and getting by. You are calling it laziness but maybe it was boredom?
Maybe after being bored and unchallenged you became "lazy" at school. I would bet that you were very interested in your own activities that you were interested in.
If we opened up gifted education to 120+ there would be enough students to have a decent sized class in suburban schools.
I'm in the 98th percentile and I thought that I was special flower until I started to study math and physics in university level. I met several people who I would consider actually gifted (IQ above 160 and intellectual curiosity to use that IQ). I quickly realized that my problem had never been my intelligence. It was the arrogance and laziness that came with being relatively smart. I could cope with everything and everyone if I tried even a little.
Many of these actually bright guys (and especially girls) had actual problems in their youth. Taking part of International Mathematical Olympiads allowed them to use their noggin and meet others like them. Getting noticed and the ability to take university classes while minor was the lifeline that gave them purpose and mentoring they needed. They really benefited from being noticed when young.
