Welp, as you can see I'm new here

My name is Stephanie, 21 years old, and I'm from North Carolina. My highest weight I remember ever being is about 293. Right now I weigh 287 pounds (height is 5'7) I am just basically going about it with eating better and exercising more. No special diet or anything like that. My ultimate goal weight is to be 140 pounds.
I have tried to lose weight many times before (yes, the "yo-yo diet"). I think what I really need would be some motivation partners to help push me along, someone to keep me accountable. I'm hoping to make some good friends here to help to motivate me! I am very excited about starting my weight loss journey here
