Is it normal that I feel like thinking and doing are the same?

Incredibly unrealistic. Lets say you are very attractive indisputably and you have a guy friend who has a girlfriend. Does that mean that suddenly you are indisputably ugly to him? Nope, you're still attractive and you would dismiss other opinions because you know you're attractive. Now lets say you're the girlfriend of the guy and the attractive girl is just a friend of yours. Was she ugly before you got with your boyfriend? Is she ugly now? Nope, she is the same attractive girl before and after. The difference is that the guy chose you over her so he already prefers your beauty, no need to come up with crazy rules that limit thoughts for the safety of yours. Thoughts like what you described gives off the idea that you must be on top of the world and no one else can have anything or else they are worthless to you. You don't want to be in the ranks of Cruella de Vil and Maleficent, you want to be an understanding female who doesn't need all to herself.
