Don't ask me for sympathy cos you're fat, you won't get it

Another week, another opinion...
Don't come complaining to me if you're fat. I don't want to hear about how you eat badly and don't do enough exercise and therefore don't fit into all the cute little outfits that your friends wear because I'm just not going to be interested...
Where did this complete lack of sympathy come from, you might wonder? I mean, hell, I am a fatty too. But, the flipside is that I acknowledge, but do not complain about it or beg for sympathy anymore. It takes up too much energy and I just do not have time for all that crap.
If you want sympathy, try not to be the source of your own problems. you can blame childbirth if you want, but after a few years, is that really a reasonable excuse? You can blame the fast food companies for making good food, but you're the one's handing over money in exchange for greasy goodness posing as food. Don't complain to me that you're suddenly feeling fat after you eat that. Get up and get your body moving. Get rid of that burger or at least a percentage of it.
Obesity is an epidemic, it's true, but it's one that's connected to self-harm if people are eating rather than dealing with their emotions (I know something about this cos this is how I got my excess kilos).
Okay, so I'll sign off with this fianl thought... How is eating bad foods en masse, which will damage the body for the longer term and not exercising any of it off, any different from damagind the external shell of skin by cutting, burning or any other method that the mentally delicate choose?
