Ok sooo....
I feel really awkward asking you all these questions, but I need the encouragement.

1) I need to lose 40lbs to hit my goal weight. I'm always nervous about having flabby skin later on (I haven't even lost 5lbs yet!!!!!!) and I'm always jittery when it comes to food, and then I end up binging and hating myself and it's an endless cycle. Basically I'm just not managing my food properly and I'm starting to think I just can't do it....!!

2) I'm having a hard time getting my butt off the chair/bed/whatever I'm sitting on and working out. I love the actual workout, but getting off is the hard part for me. What do you guys do to get yourself to workout?

3) I start off the week with a great intention and plan and yada yada yada, but by Wednesday or Thursday everything is screwed up and ruined. Any tips on maintaining the positive energy I lose...!?

School starts on Monday for me, so I'm even more nervous I'm gonna fall and gain even more.
I'm sorry about the rant- I just need some tips and help right now
