Need a few 'helpers'

I'm new to this. I had another app on my phone, but this one is SO much better! So I need a few people that I can console with when I want to get that extra serving or sweet snack I know I shouldn't eat. I am 20 years old 5'8" and I currently weigh 193lbs. I would like to get down to about 150 or so. Ideally I would like to fit into a size 11 or so. So if there is anyone that is in the same situation or willing to help let me know, THANKS!!
