UGH!

So... things have been plugging right along. Almost too much of a routine for my taste now that I've settled in on running as my main cardio source (to train for the half marathon I've now signed up for - more on that later I guess I may have forgotten to mention that). 
When I cranked out the 6.23 miles a few weeks ago, my knee bothered me just a bit, nothing major.  Then I went to do a free workout with a trainer that Saturday, and I was doing squats, and think I may have hurt my knee somehow. I continued to run the following week, and it didn't really hurt, but I had been icing it quite a bit.  
Felt good the last 2 days, and I went back to the trainer tonight.  Seems to hurt again.  Icing it again.
I've taken this week off from running to help it rest and heal.  I hope it works!
I really don't want, or need a set-back right now.  I've come too far, and still have a long way to go, to get discouraged over an injury.
To top it off, I think I've hit a plateau with my weight.  I'm not showing any weight loss for 3 weeks in a row.  In fact, I gained 2 pounds over the last week. That's the first time that happened since I started this journey!  I'm chalking it up to Easter, salt, and lack of water for now.  But I really want to see a decrease soon, so I don't become discouraged. (I'm the person who needs to visualize the result to know my efforts are paying off).
On a positive note, my clothes do fit better, I've decreased a size in my shirts (to an XL now) and am close to going down a size in my pants. I guess that's progress, I need to keep that in mind too, and hold on to whatever positives I can.


I REFUSE to let myself go back to this!
