Trying to not stand out as much as possible

When i was in grade school, i remember not being well liked because i was so meddlesome lol. And i remember i wanted to change myself so i could be well liked and I've started doing that since i was in middle school. Since then, i've been surpressing myself from getting over excited, trying to act cool, never stating my opinion, and basically not saying or doing anything that could offend others. And now i became the most unnoticeable person lol. No one knows how im really like, not even my close friends. And when people describe me to others, they said that im a very nice person that doesnt get involved in any trouble. Oof. But i enjoyed being alone like this. Anyone here have similar experiences?
