My emotional responses tend to be a little.. off...
Or don't scale to the severity of the issue
Is this consider a depression related issue or something else?

Basically, when something really bothers me, I'm shielded and emotionally unresponsive. And I obsess over little things like they're the end of the world.

When I was physically abused over and over again by a boyfriend, I behaved as if nothing was wrong. And there were no tears at the time. But when some thug inappropriately hit on me, I went home and cried myself to sleep.

If my best friend died, I don't think I would cry or let it affect daily life at all. But if someone I met in a random online video game starts ignoring me, it might bother me for days

When I lost half my life's savings, I didn't blink an eye. But I was emotionally burdened for two weeks over <$100 of stuff stolen out of my car
