Hey, I just joined today and wanted to say hi.
I'm not quite a 20 something, I'm 19, but after looking at the teens only group, I felt more comfortable here. I've just started seriously working on my weight this week although I have struggled with it my whole life and it has gone up and down. Over the past year I have gained alot of weight from starting college, and having major back surgery. I'm hoping to get down to the weight I was before my back problems and then work from there, that makes my short term goal about 215. I put the weight of fast because I couldn't move much and was on medication, I know it has to come off slowly, and I want to start taking it off today.
Um, so to introduce myself some more, my name is Sarah, like I said I'm 19, I'm in college and I'm looking for a little motivation and support as I try and lose weight. Any suggestions are welcome, and I hope to keep up with this, you all sound so nice and interesting, and i could really use the support.
Well thanks for listening and I hope to hear from you guys soon.
I am new as well and am young (21). I am in the same boat as you. Congrats on choosing to make a healthy choice. From what I can tell from this site you have all the help, support, motivation ect to get you to your goal. You go Girl!!! 
Looking back on it, I wish I could have just driven right on past! Congratulations on making a choice to be healthier, its a tough one and we all know that.
