I haven't gotten to the point where I feel like I need it, yet. I'd prefer not to ever get there. I was speaking mostly for myself, though, I wouldn't presume to comment on how things are in your head. :P
Well, with depression there's often no help to be had short of medication. I wouldn't feel too bad over it, though little things like keeping someone company often help more you might realize.
I'm unfortunately quite used to it. Half the reason it gets so bad is because I don't even notice when it's merely mild and building up.
I tend to be really obsessive about my feelings, though. I have no idea why. It gets to the point where I get really frustrated with other people who can compartmentalize stuff and not break down the way I do. And being told I should just "get over it" or "get out there and start living your (my) life" by my family certainly doesn't help.
I find that when I stay shut in for days at a time, time starts going faster and faster and I lose track of what day it is, and I stop taking care of myself, and my depression gets out of control. So I kind of need to get out once in a while to keep myself level-headed.
