You can do it!
Hey I'm the same height as you, also with around 20ish to lose

I've lost 54 so far.
I respect anyone who is losing weight while in school! I don't know if I could have done it! I started up again in May, just as I was finishing my Master's in Education. Right now I'm teaching full time, but honestly I don't think it's anywhere near as stressful as going to school full time.
