What concerns me is your statement that you don't consider yourself
skinny and the mention of depression
It's difficult without knowing how tall you are but the thing is that anorexia
is all bound up with self image and how you think of yourself. People allow
themselves to attach their anxieties onto a single - false problem like weight.
There is a tempting illusion that weight is at the root of all your problems
and anxieties and if only you could lose that little extra weight things would
turn around in the rest of your life.
It does sound as if you may be becoming a little obsessional and now may
well be the time to look for a bit of help before you start to slide.

There's a help line in the top right hand corner - why not give them a ring
Remembering that I'm in no way qualified I would suggest that you try to
think not of weight but of fitness. Take up a sport, it'll help you keep at a
good weight and exercise is well known to be very helpful in things like
depression and anxiety.
