Halfway to Goal and Need Motivation! (pics)

Hey everyone.
My name's Becca, I'm 21, and I've been a member on this site for a little over a year.
In the past year I've lost about 62 pounds (give or take due to daily fluctuations) and managed to get myself off of blood pressure medication (BP meds at 21? Crazy, I know.).
I'm 5'11" and I started out in May 2013 at 302 pounds. Stepping on the scale at a doctor's office one day gave me a shock. I was over 300 pounds. I had always been a chunky kid and teenager but never really saw myself as "that big". But boy did my opinion change that day. I knew I had to do something. I knew I needed to change my life, and so I did. I started an active job, started making better food choices, and got myself on a healthier path. I've been pretty successful thus far, even with the plateaus and bumps in the road. My Ultimate goal weight is 180 and I'm about halfway there. I've had a throat infection for the past month, am currently on my second round of antibiotics, and I'm pretty bummed out that my weight loss has stalled due to my current inability to work out besides some walking. So now's where you guys come in. I could really really use some inspiration and motivation right now to get me past this stall, to where I'm healthy again and can work out more. Thank you in advance for any contributions
