Im 5'2 and been smaller than a 0 , I was always ill , depressed and tired. I was stressed and survived on ready meals crisps and not much else. I could never wear any womens clothes and had no bust to speak of. My shops were hennes kids , gap kids (I worked in Gap at the time , everyone laughed at me), & if feeling frivolous and decadent designer kids from Harrods (or just fed upo with not being able to wear real clothes for my age). I was like this until I got married , took depo provera and seroxat. Ill never be that size again and to be honest dont think Id be very well if I was.
I really dont know what size I am now , I seem to be wearing 12's,as my hips are very pear shaped. If it wasnt for the 2nd pregnancy muffin , I think Id feel ok in myself.
