You're stuck. I get that. Getting below 235 seems like the impossible right now. You are amazing at self-sabotage. The scale showing 240 again today proves that.
What I don't get is WHY??? What is it about 230 that seems so scary to you? It has to be fear that's keeping you from moving forward. It's not lack of knowledge. You know what to do, and how to do it.
You've been doing great (for the most part) with exercising and running. Last week you even ran your first sub 15:00 minute mile! That's HUGE! That's FIVE MINUTES less than when you started, PER MILE!
I wish you could see what other people seem to see. And stop being so damn self-critical. You're not going to be perfect, ever. No one is. Get over it and on with it.
Rather than focusing on what you can't do right now, it seems about damn time we start focusing on what you CAN again. You CAN run so much farther and faster than you could in October. You have stuck with this since then, too. That's 5 months. That in and of itself is amazing. This is a life change for you. Not something temporary. Better get used to the idea, though I do have to say that your outlook for the most part is a positive one. Not wanting to lose any more ground is a good place to be.
I know you can do this, and more importantly, I know you WILL do this. We just gotta find a way to get around, or over, under, through, whatever, this boulder in the road!
P.S. You finally found a 5k to run! GOOD JOB! The Salt Lake City Adoption 5k Family Fun Run and Walk is only 6 weeks away. Stop being scared. You can do this. You will be great! :) And I know there will be a few people excited to hear about your first race. So breathe. just breathe.
