Aw Heather honey! I'm so very glad for you - it's about bloody time!
I wouldn't worry too much about the weight, unless you are very overweight - like BMI 28+. Even though I am still a bit overweight, I am so much more comfortable in my body right now, that all those old feelings of "must lose weight, must look perfect" have quietened down a fair bit. Sure, I still want to lose the weight, and get twinges of jealousy when I see very lean, toned women, but I know that by eating right and exercising I will eventually get there.
Even more positively, this more positive self-image has eaten into my old eating disorder habits significantly. I used to be a huge binge-starve exercise bulimic, but since starting HRT that "This is my last one, so I'll have lots, make myself sick and never have them again" drama is going away.
So I'd start the HRT. I think for most of us, when we are in denial, we confuse our gender-related body issues with weight issues, even while binging, in many cases, I think, in order to gain weight and be more andro. Once your body starts changing to the shape it is supposed to be, things will even out - just don't look at too many airbrushed cover girls!
