I am overweight (but on track for loosing weight gradually), but not for that reason.
When I get depressed, it has the effect of practically killing my appetite and in those times I have to remind myself I need to eat something (of course it might not be somethgin healthy that I end up choosing, but its not eating to feel better either).
In normal conditions, I think it has as much to do with an unhealthy fast food diet of conveneince as anything else (part of what I've been trying to seriously cut back on). I also really like coffee, and well, I like something sweet to go with it to contrast and enhance the bitterness of the coffee and well that stuff aint so good for me (another part of my diet I've mostly removed now (the sweets, not the coffee)).
For the time being, I'm considering myself "probably INFP" but still a touch of uncertainty about it.
