I have often described my emotions as muted, never elated nor furious. The only emotion I ever feel fully is sadness; deep deep sadness. I don't live in a sad state, but I can feel it, unlike the rest of the emotions.-Diana
You describe much of what I have felt my entire life. No real happiness, just a weighty sadness. There have been times I have felt rage/fear as I came closer to my crisis that tore me asunder. But it seems safer to feel nothing over the course of my life. Because to have felt it all as I went along would probably have killed me.
And when I do feel what I sometimes think is happiness, I often cry like there will be no end to it. Stuff like looking at my daughter when she's asleep, or seeing a parade and fireworks. It's overwhelming. And then I worry that someone will notice which makes me feel stupid.
But then I realize: I am making up for at least 50 years of not being in touch with my feelings. When it hits even a little at a time - it's a lot.
