I am having difficulties with my gender?

I have always been a tomboy, but lately being a woman is really ******* with my head. I am pretty much straight. I am in a relationship with a man and we have a child, but lately I can't stand being a woman. I have always identified better with men and gotten along better with them. I like sports and getting dirty and working on cars. I know more about a lot of sports stuff than most guys. But I also am feminine at times as well. So, anyways, lately... I keep fantasizing about a sex change. I hate being a woman. I am also an attractive woman so I feel like no one takes me serious because of it. I feel like I miss opportunities because of it. I have also been told that because I am a woman, I can not participate in certain things that I am passionate about. I get shunned and treated like crap even though my talent exceeds the talent of other candidates for what I want to do. I was told by a friend that these guys don't want to do things with me because I am attractive and it intimidates these dudes and it will ruin the group if one of them likes me and it just causes drama. I hate this and now that they brought that up I have been wanting to mutilate my face so my looks arent a problem. I have wanted to smash my breasts or just remove them. I don't know if I would even want a penis. I just want to not be too attractive for something. I hate being hit on, I hate gender stereotypes, I hate that these people are objectifying me. Has anyone ever been through anything like this? I hate being a woman. We get cheated on more and its like expected or something... we get treated like we are less than a man, we get hit on a lot which is the most annoying thing to me ever. I hate it. I really wish that my cells would have split while I was developing in my moms fallopian tubes so I could have been a man. I hate feeling such inequality and it is making me crazy. Is it bad I wish the world would end?
