Re starting MFP... again!

Well folks, my birthday has passed and i ... gained... 8 lbs :(
So, it's time to get back at things!
Feel free to comment or leave tips that helped you. I've had such bad luck with my weight loss lately and feel that I'm probably doing something wrong.

My new self:
Current weight: 128
Goal weight: 110
Age: 20
Sex: Female

Just thought I'd re introduce myself :) Can't wait to finally become a better me!
