Thanks all! I don't know how I could cope without the support from the people here.
There were a few more things that I didn't have time to write about until now. I'm gonna try to put them down now, because they've been festering most of the day, and I'm trying not to be angry. Angry won't help.
First, they do not like my name. At all. Among other things they complained that it's juvenile, sounds like a stripper's name, is not "racially" appropriate, and that they weren't consulted in the process. I told them that I would let them help pick out a name, but honestly, I like Tamika. It's how I think of myself, and I can't see myself being happy changing just to please them.
Second, there were a few pushes about my appearance. My father is absolutely certain that I'm too masculine to pass. He opined that he doesn't see how I can make a woman out of "this" (he gestured to my body). Honestly, despite the concern trolling, this one didn't bother me that much. I have rounded features, no visible Adam's apple, small hands and feet, and a relatively short stature. I'm not saying I'll ever be a model, but I think that with the right clothes and the right make up, I can pass easily.
Finally, there were numerous tactics to get me to delay HRT. Two I've talked about, regret and certainty, were of no use. I could regret it, yes, but I could also regret walking down a certain street on a certain day. I could regret NOT taking them. There was a third, more practical concern, that they voiced. I'm currently working on contract with a large corporation. They want me to wait to start HRT until I'm permanently hired there. I reluctantly agreed, but I'm not sure whether I can hold to that. It was an olive branch, and it makes practical sense, but if this were any other condition I were coping with, they would not want me to wait to start taking medication. I'm still weighing it, and I haven't even seen an endo, but if push comes to shove and the dysphoria grows unbearable, I'll start HRT even in the face of the promise.
All of it gets down to the deeper issue. They think their role in this process is bigger than I'm willing to allow. I want their support and their love if they're willing to give it, but I'm the lady behind the wheel of this car. HRT, name, passing.... it's all going to be by my hand in the end. I have to do what I know is right, even if it results in me doing it alone. That's not going to be my first option, I'm going to try to work them around, but I'm prepared to do it if it comes to that.
