Looking at it the other way ... how about the GOOD things about being a transsexual?
Here are some of mine ...
When I was young and could pass as a boy or a girl, I loved being able to flit from one side of the gender-boundary to another - like an undercover double-agent!
As a writer, it really helps me create believable female characters, write convincing sex scenes from a female point of view etc ... tho I do sometimes have trouble with my male protagonists!
I love the fact that - like Guapa said - I can enjoy 'boy things' and 'girl things' ... I'm crazy about sport and military history and the business pages ... AND I love fashion, interior design, girly chit-chat. You don't have to be TS to be like that - but it helps!
And finally, if I weren't TS, I'd just be another pampered WASP ... I actually welcome the fact that in one part of my life at least I know what it feels like to be in a misunderstood minority. I read 'sex-change shock' headlines in the papers, or hear people talking about 'trannies' and as much as it hurts or angers me, it also reminds me that so many other people have to live under oppression or discrimination that is a thousand times worse than I've ever suffered, and maybe I shouldn't be too quick to patronise, judge or criticise them, either.
