Needing some friends for motivation!

Hi I'm a 20 year old at University studying English Literature.
I'm looking to lose 3/4 stone with a combination of eating less and more exercise (which I've never been a fan of!)
I've been diagnosed with having an underactive thyroid and PCOS which basically means it's gonna be even harder to lose weight! So I'm not looking for any sympathy just some motivation to keep me going and some encouragement to get my lazy self doing some workouts to try and shift some of this weight!
:D
