Last week I had a panic attack. Actually, I had a series of them. If you've never had them, the best way I can describe them:
Add those up, and experience them all at once, for, oh, about a half hour. That's a panic attack.
I only had one back then, but it's been building for a long time. I'll need to go see someone to deal with some issues I've been putting off for a long time. This has been building, by the way, for several years. For several years I would avoid going out to do errands because I "didn't feel like it".
