Long time away

Just got back from 5 months of travelling, had the best time of my life but unfortunately I have come back weighing a considerable amount more than I did. I am ashamed to even say it but I now weigh 137 pounds...horrific! In one year I have gone from 107 to 137 truly awful. Enough is enough so tomorrow I am starting a healthy eating and exercise regime, I want the control I once had back. I am excited to see the scale going down again though, thinking positive.
