I feel ya trueblue, it's a lonely path that many of us walk. Thank you for your rant, and I hope it helped a little bit. Things like this can be very helpful to others lurking around the forums, who might read it and not feel so alone anymore. (like me!)
I too have built a facade to hide my true self away. It was such an effective one that for a while, I even managed to hide from myself, but that did nothing but delay the inevitable and increase the pain when I finally started taking stock of myself.
I've tried making the best of life as a male, and after several years of sustained, exhausting work, I've accomplished more than most people in every area except my social life. It seems that you, like myself vastly prefer to engage in social interaction - both romantic and platonic - from the polar opposite gender role. It is extremely difficult (but not impossible) in my experience to find a way to make this work without changing your appearance, and I've come to the conclusion that if I don't transition enough to confidently present myself to other people as the other gender then I will be spending the rest of my life alone. I considered this scenario, and there would be moments of contentment, but when I'm laying on my death-bed, I can say with certainty that continuing on that path would be my greatest regret.
You said that you want to lead a happy and fulfilling life. What do the words "happy" and "fulfilling" mean to you personally? What exactly do you believe would make you happy and fulfilled? What decisions might you regret when you are old and gray?
There is indeed much more to life than gender dysphoria, but remember that the gender dysphoria itself isn't the core of the problem, it's merely a symptom. If your social dissatisfaction is something that is fueling your dysphoric feelings, then the only way to mitigate them is to find a way to meet these neglected needs. Telling yourself that there's more to life and forcing yourself to push through the dysphoria is akin to ignoring those dirty dishes in the sink. They'll still be there the next time you enter the kitchen, most likely with a few more added to the pile.
I hope I didn't sound too preachy there, and I realize that you were just venting, so feel free to ignore me. As with everything on forums like this, it is only my opinion and that which I have found to be useful for myself. I hope that it might be useful to you (or anyone for that matter) as well.
