Well I have definitely went through the roller coaster of emotions and doubt due to transitioning. I never completely hated and despised my male body; I was more neutral with it like you described. I first had thoughts that confused me about my gender when I was around 7 or 8 and throughout my teenage years I repressed these thoughts and did everything possible to try and live my life as a "straight male".
I played basketball 3 out of the 4 seasons and I did track in the off season to stay in better shape and I enjoyed being competitive and being able to play physical in that aspect, but I didn't fit in otherwise with other males. I didn't date until I was 17 and once I started dating, I think it just added to my dysphoria, especially when I was in a committed relationship. I could tolerate playing that straight male role for a while, but once I got farther into a serious relationship, I subconsciously was extremely bothered by pretending to be someone I'm not.
When I first decided to transition, I was excited and extremely motivated and when more and more time went by, I was able to think things through better and I realized how big of a decision I truly made. That freaked me out a little bit and I considered the thought that maybe I wasn't actually trans and I just needed to try being a straight male again and find some other sort of outlet. It felt as if I was arguing with myself and I was tearing myself apart, but for myself I understood that transition is right for me and I used key thoughts and events to push me forward again. I constantly remind myself of when I was really young(like 9) I would pray to God at night to wake up a little girl in the morning and wouldn't know exactly why, it just felt right at the moment, or why I would wear my mothers clothing when she wasn't around and it made me happy.
I'm at about 5 months of hormones now and I still have doubts from time to time, and I worry about my transition way more than I should, but I'm just going to keep pushing along and doing my very best to be honest with myself. I look at myself and I ask if I'd be happier as a female or a male and the answer is really obvious for me. You're not alone, just be honest with yourself and you will get through everything! I wish you the best!
