Hey man,
Welcome back. I've definitely been there, funnily enough also after top surgery. My feeling on it is that my chest was the most obviously thing that made me female externally, and having to bind all the time was a constant reminder that I wasn't "male". After top surgery, I'm flat, there's nothing that would make anyone I pass in the street think that I'm not a dude. So then I started to fixate on the things that only I noticed - my weight, how my fat was sitting, everything downstairs.
I got super depressed for a bit, took a break from any kind of community interaction, and just settled down to do research on what my options were. I knew if I wanted to get any kind of bottom surgery I'd need to lose weight (I'm the same height as you and was around 200-220lbs at the time). So I started with that - I think also having the same thought process as you where maybe if I lost enough weight the growth I had would be more prominent and I wouldn't need surgery.
But ultimately, I'm down to 170 now and that area seems to be the one part of my body where fat won't budge. Having researched bottom surgery for over a year now, I'm very comfortable with the conclusions I've come to about it and feel much more confident going into it.
As far as secondary things like my face, my height, size of my hands, etc. I think in general we are more critical of ourselves than anyone that we might meet would be. While I do still occassionally think my face looks feminine, I think the "total package" I present is viewed as 100% male to folks I meet, so in that sense I don't need to put much time into worrying about it. T has been really good to me, especially post-hysto. I can't remember when you started T, but maybe you just need some more time to get there?
I did have a lot of issues with motivation in terms of eating right and weight loss. Some weeks I'm really great about sticking to the meal plan I've setfor myself, some weeks I want to go to Taco Bell every day. Some weeks it is easy for me to stop at the gym on the way home from work, other weeks I can come up with every excuse in the book to not do it. The best motivator I've found is thinking about what will happen if I don't do something. Will I gain weight? Will it take surgery off the table for me? Would it compromise my surgical results? Would getting any bigger make me less passable? Weighing the choice to work on it or let it go in the context of what my goals are did seem to help motivate me.
I understand what you're saying about having no representation of transguys that don't fit the "ideal male body". And while that's a valid concern, I think the issue is more on the side of what the media wants people to see. How often do we see guys that aren't ripped on magazine covers? How often do you see a bigger guy that isn't cast as a big dude in a comedy movie, or he's cast in a role where he's immediately unlikeable? The mainstream media doesn't like fat people. And in our effort to normalize and fit in with their standards, we've created this "trans paragon of manliness" that has great pecs and a 12 pack. Media imagery has an effect on self esteem, but it does seem to vary from person to person in terms of impact.
I've found that thinking about my body in terms of health and happiness is effective in getting past that. As in, I may not have that "ideal body", but my doctor says I am healthy and the lifestyle I currently have gives me a lot of happiness. If I didn't have both of those things, then something needs to change about how I'm living my life.
Hope this helps! Feel free to message if you need to chat.
