Given what you have shared, you were bullied and led to believe you were less than. You have decided to prove them wrong and are putting in a lot of effort to make financial gains for yourself. Yet, because of your history you can't really let anyone in because it's the very thing that had hurt you when you were not able to understand and better deal with it.

You have always hated those who seem to have it easy and tend to get things handed to them. It's very possible you want them to feel the fragile you felt so long ago and tend to still carry within you.
