Over the last two to three months I have become increasingly depressed, to the extent I look in the mirror and completely hate myself. After having DS last year, I gained loads of weight, I managed to lose nearly two stone in the following months, gained about half a stone over last Christmas and have been on a diet ever since then. However, my weight and size has stayed exactly the same, irrespective of what I eat or how much I exercise. This is what has made me think, together with how low I am feeling, made me think that maybe I have an underactive thyroid. I can have a couple of good days, followed by a day of constant crying and feeling really low about myself. Today was one of those low days, what triggered it was weighing myself. I managed to lose 4lbs last week, which I thought was great, but sticking rigidly to my diet again this week and I have put 2lb back on! I would rather stay at home because I am so paranoid about my weight and am frightened people are laughing at me. I am not excessingly overweight, maybe three stone and am a size 16, but I used to be a size ten. I know I will never be that but I would just love the clothes that U have in my wardrobe to fit me and I feel and look good in them. I used to be so confident and now I shy away. My DS is about the only thing keeping me sane. Talking to my best friend today, who is also a HV, she thinks I may have PND. I must admit I didn't realise this would be possible with a DS of 16 months. Comparing the symptoms of the two, I feel more likely to be the thyroid, but could I just be in denial, and why would PND stop be from losing weight? Any advice/help would be appreciated.
