From everything you wrote, all the strong feelings about how much you don't want to be female and desire to be male instead, it sure doesn't sound like you're imagining anything to me. One thing that you wrote that caught my attention was "I like to think that I'm male, but everything about me screams female, woman, girl, etc." Just because you feel like certain parts of you seem more feminine than masculine, that doesn't mean that you're imagining things.
I know my situation is different from yours since I enjoy being female and male, but I can understand feeling as if my thoughts and feelings conflict with other aspects of myself (in my case, my appearance and my personality). For example, I can be very emotionally sensitive, have a lot of feminine interests, have long hair, wear make-up, wear skirts and dresses, and generally have a very feminine face and body type. All of those things have made me question many times before whether or not I am truly transgender. But then I stop and I realize that my personality, my interests, and my appearance don't change the fact that I feel just as happy, if not happier, being dressed as a male and referred to as a male. None of those things change the fact that I sometimes wish I had a male body instead of a female body.
