Hi Law Ram (I'm intrigued by your name!) - like others have said, you're in the right place for support. Everyone always rallies round whenever anyone has posted feeling low as we all know the feeling only too well for one reason or another! It's horrid when you get to that rock-bottom moment when you look in a mirror and hate what you see, whether you hate the fact that you're 10 stones overweight or 1 stone overweight. And yes, it's hard not to compare successes and statistics! I'm surrounded (in real life) by friends who weigh a skinny 9 1/2 stone and lament that 'extra' half stone that makes them feel so fat. It makes me want to get my belly out and shout "No, THIS is fat, you skinny *****!!"
But I also know that at 14st 8lbs, although I was the biggest I'd ever been and none of my clothes fitted and I felt hideous and miserable, there were plenty of people here who wanted desperately to be that weight and probably hated me for saying I felt fat. And that, at 13 stones now, I feel skinny and amazing, even though I know logically I'm still 2.5 stones overweight 'on the charts'. It's taken me a long time to be able to start putting it all into perspective.
Can I suggest a slightly controversial mental exercise? Have a look through the forum (in the weight loss sections rather than the exercise section) and focus on the posts and stories by people who are at a much higher weight than you. Have a look particularly at the positive, happy posts from those who have successfully achieved great weight losses from, say, 22 stones to 18, or 18 stones to 16. Ignore any posts that are negative, or from people at a lower weight. Just as a one-off exercise I mean, not permanently

They are the people who are striving to be your weight.
Maybe also try some self-affirming techniques to begin to raise your self esteem? My favourite one is to add the words 'but it doesn't matter' (in my head or out loud) whenever I have a negative thought. Like, 'I was going to go for a walk today but it's raining... but it doesn't matter, I'll go anyway!' or 'I'm feeling so fat today... but it doesn't matter because I've joined Minimims and next month I'll be less fat!' Sounds corny but it does start to become a habit and it works!
I'm looking forward to following your journey to health and happiness.
