Back again

I lost 30lbs using my fitness pal about 3 years ago. I kept it off for a year. I started dating the love of my life and gained back what I had lost plus an extra 20lbs! I honestly did not realize i had gained that much until i stepped on the scale. I knew i was gaining weight but not that much! So i'm back! Back to counting calories and my friend and I got a gym membership. Looking to lose 50lbs at least! Lord help me!
