Second time on MFP, 22 and need support!

Hey guys! I used MFP a couple years ago and lost about 15 lbs, Then I moved and life got complicated and I just slowly fell back into my old habits. And gained all my weight back. But I am ready to do it again, for good this time! Anyone else similar age/goals or anyone at all that wants to add me and help support and motivate each other would be more than welcome!
