You have been writing some exceedingly self-centered, triggering posts. It is time to get a grip. You have plenty of other things to deal with besides your love handle hang-ups. No, you don't have a placement yet, but you can think of what you want your classroom to look like and what your management strategies will be. You can draft a letter for your students' parents. You can think about data tracking and organization. You can actually start using your damn planner.
Oh, and you can enjoy yourself, too. You're living in a beautiful apartment with your fiance. That's quite a good thing.
And you can work on your body if you want to. You can get back to where you were before Institute - but it is not going to happen overnight.
Get over it. Get over yourself. Get a grip.
