You're absolutely right. Sometimes I wish I simply was cold as a stone inside. In fact I tried to achieve this for much of my life, and let's say the results have been counter-productive!
I can't go my whole life shielding myself away from my emotions, and ultimately people. I can't keep everything inside either (something I'm too good at IRL), it becomes anxiety which isn't any better.
At least I learned to let the dust settle before making decisions. But my point still stands, even if I can keep myself from overreacting or creating drama, I'm doing myself no favour wasting energy like that. It's much wiser to spend that energy on figuring out why I'm like this, why I've been feeling so different from other people my entire life. My father is convinced as can be I'm one of those people called "gifted". The amount of arguments he brought supporting this (and backed up by books on the matter) is very difficult to ignore, so he may very well be on to something... Maybe I should see a psychologist specialized in giftedness (thankfully there are some within driving distance of where I live) and figure this out once and for all.
I'll probably stick around in the meantime, but go (partly) silent for a while (or not). Nothing is definitive at this point.
And thanks for those kind words. I really don't want to appear in need of external validation (I'm aware of how unpleasant this attitude is to others), but it was heartwarming to read.
