Looking for support buddies

Options
I've always used MFP in spurts, but since I'm graduating college this year, I'm determined to get rid of the college weight. I only have a couple of friends on MFP, but I would like to have more or maybe join a group. I have many questions about weight loss such as loose skin after loosing weight? I'm really worried about that, since I'm only in my early 20's and would like to wear bikini's and such. I'm currently 5'1 and 180 lbs and would like to loose 70 pounds to get back down to my pre-college weight. I'm really nervous about this weight loss journey, but I don't want to be 180 forever. If anyone would like to join my journey, feel free to friend me. Thanks!!
