Conquering my thought life

Every emotional response is based on the belief of a particular thought. Say, if someone doesn't like me for whatever reason, an emotional response is to feel rejected. This can be translated to, When someone doesn't like me, it is my job to feel rejected. Or, more specifically, When someone doesn't like me, it is because there is something wrong with me. The last statement reflects where some of the pain could come from. After identifying the belief behind the emotional response, I have to identify that the phrase "it is because there is something wrong with me" is NOT a true statement. How can I make this a true statement? To make the transition easier, I will change it to something that does not reflect on me, something does not give a negative emotional response. When someone doesn't like me, that is their business. If something isn't my business, I'm not going to care about it. And it is still a true statement. What people believe about me is actually none of my business, and it is not a reflection of me but only a perception. This practice seems to require a lot less effort than simply trying not to feel rejected. I know and understand this, but I have to remind myself of this practice because some of my beliefs about myself are currently under a stronghold that will require time, effort, and patience to break. It is consciously breaking the unconscious. I'm up for it.
