Need Motivaton!!

Options
Hi everyone. My name is Sarah. Im in my mid twenties. I got married last year and was the most fit I had ever been in my life. I weighed 130lbs and was working out regularly, eating right, and feeling great. I started to gain at the end of last year and am now 35lbs heavier than I was when I got married. I need some word of wisdom to get me motivated to getting back to where I was a year ago. I appreciate any comments you have for me. Thanks everyone :)
