New at this and could use encouragement!

Hi folks I am new to myfitnesspal and i dont have a clue what i am doing. I am a part time student who works in Boston. I have had a lot of downs and very few ups in my life the past two years and that combined with acting as a surrogate for my cousin who couldnt have children on her own has caused me to gain about 60lbs, as someone who had always been skinny, this has been a new experience. Now that I am back on my feet i feel that I need to tackle this weight problem. All my friends are quite slender and don't really get what a battle this is. Any support or tips on healthy dieting would be great!!
Thanks and Good Luck Everyone,
Rachael
