Do I sound like I'm FTM? I tired of doubting myself.

I am pretty sure I'm FTM, but sometimes I get scared that its wrong. I guess am asking for somebody to give me the check yes because that always makes me positive. So here's everything I guess:
Since I was little I've seen myself as male but never really put much thought into it. I would always want to be a male in all of the imagination games all the kids were playing (of course they laughed and called me a girl and made me be some female person). I preferred the guys toys and would get mad if I was given the girl one. I remember once I told my mom to say I was male at burger king so I could get that G.I. Joe . Then I got a little older and was told I had to start wearing bras >_< I fought it for months. I would get tissues and tape them around my chest so my mom would think that I was wearing it but when I got to school I would take the tissue and throw it away. Eventually she found out and I was forced to. I remember feeling miserable and humiliated when getting those and shopping for clothes I would look longingly at the boys side. Then the bloody thing happened and things got worse. Last year I found out about trans people and the more I read the better I felt, finally knowing who I was. A year later, here I am, out to friends and a few others and passing 90% of the time.

Here's the kicker. My mom and two of my friends tend to invalidate my gender and just when I felt like its all there and figured out, they got me baffled again. This makes me feel crappy. It makes me lose my confidence and make me doubt myself as a male.

I just need somebody to say "hey, you're a man and they are ignorant." I guess because this makes me feel more dysphoric and sucks so much.
