...according to that link all infps have major depressive disorder

Unfortunate.
I hear counseling and medication can work wonders.
In the link, most of the qualities of an infp are my worst qualities. The qualities I have when I'm at my most depressed or dysfunctional. However, I want to point out that I don't think marijuana should be legalized, never have, and I'm fine with crowds, and I'm not a hermit.

As for the ENFP qualities
outgoing-probably
social-define social?
disorganized-only 4 or 5 days out of the week...
easily talked into doing silly things-silly, yes, stupid, no.
spontaneous-only compared to some
wild and crazy-did Jung really imply this? No, you won't see me on girl's gone wild and there are no photos of me dancing on table tops. I don't even kiss strangers or throw things at people.
act without thinking-well, I have this issue with my brain mouth filter. It's more "talks without thinking"
good at getting people to have fun-....am I?
Pleasure seeking-um...define this.
Irresponsible-um...maybe
Physically affectionate-ok, this isn't fair. I'm very physically affectionate with people I'm close with, but I'm not close with many people. Also, I would be MORE physically affectionate but my religious vows are toward celibacy and physical affection doesn't really promote celibacy (at least not for me) so I can appear standoffish, but it's not my desire.
risk taker-I moved to another country, twice, and traveled by myself through Europe. Does that count?
...
ok, you get my point. I'm going to shut up.
