I've never been diagnosed with depression (one pDoc suggested manic depressive and current t says I have the signs/symptoms but i'm just letting you know "i'm not official"). But in my experience, my depression is having a lot of emotions and becoming overwhelmed and eventually numb.

I can be with a group of friends, all having a good time. And one (just one) little comment can make me feel like they don't really like me, they're just putting up with me.

I start to stress out easily and tasks become so overwhelming that I can no longer do even small things in an appropriate time.

I get really snappy at other people just because "I don't feel like being bothered"

I want isolation or I want to be around someone (anyone) a lot. (Not always the best coping mechanism).

And my most common sign (which is actually admirable to some people) is my lack of caring about anything. Things that would, should, stress the common person out, I'm usually like "You know what? Just fudge it. i'm over this."
