Fell off the wagon and ready to get back on! 28y/o, 5'9"

Hi there! I have been active on MFP for quite some time now, but the friends I do have, do not really interact on here it seems. I want some people who are active and like to comment, give advice, ideas, encourage...I will love to do the same! I am 28 years old, and have a pretty inactive lifestyle. I have no kids, husband...or really anything to keep me super busy. I work retail and am just trying to get by. I typically will do really well for a few weeks at a time, and then fall off the wagon for whatever reason. I was only about 20 lbs from my goal weight, about 3 months ago. And now, I am 35 lbs from my goal weight. Yep, gained 15 that I lost in just a few months. I am so disappointed in myself! I am READY to take this serious but could really use some friends for encouragement! I am 5'9" and currently 192 lbs ish. I would love to get down to 160 lbs. Please add me and let's do this together! -Alicia :)
