I did the same this time last year. Be prepared for the journey to be a ruff ride with a lot of ups and downs emotionally but its so worth it! Its at the same time the hardest and best thing I have ever done for myself. The trick is to go in knowing that its going to have highs and lows and there are for sure going to be unpredicted challenges along the way but you can work threw it all one day one meal at a time. Then one day you will look back and say wow I really did it this time.
