Major Wake Up Call!!

So, a lot has been going on since our trip to London. I met with the nutritionist at Kaiser and she was very nice and was able to give me a few tidbits that I didn't already know. She was able to be more specific as to what my calorie range should be. That was a big help as every site I checked had different numbers. After reviewing about a week's worth of food tracking, she determined my diet was OK although I could add a fruit or so a day. Her conclusion was that increasing my exercise is the key for me. (No duh!) At that time, I was starting back in with the walking and was only doing 20-30 minutes a day. She said if I would increase that to 40-60 minutes, kept calories the same, I could lose about 15 pounds by September (this was first full week of June). She recommended I call a health coach at Kaiser for continued support. I was happy with the meeting and ready to get back on track.
I started walking routine and within 3-5 days I was having significant pain in the back of my left knee. I decided I should rest it for a couple of days (good excuse, huh?) Well, time marched on with no exercise.
At the end of June we went to the lake for a long weekend and I took a terrible fall off the boat onto the dock. Landed on my left shoulder and knee; awful bruise on my right calf. It was a bit of an emotional breakdown for me also---aging, falls, balance, weight----I was angry about all of it!!! My dear hubby "talked me off the ledge" but, boy, my left knee hurt like heck. There was no bruising and little swelling. I stopped walking and spent as much time as I could with my leg up, trying to get that knee to heal. Doctor? Why, no, thank you. I will just sit here day in and day out doing nothing.
Last week, at the lake, we had ceramic tile or hardwood throughout. My knee ached 24/7 and I was having significant swelling. So, I finally called the doctor. DUH!
Saw my primary care doctor (I will be changing doctors by the way, but that's another story). I know I have posted as being at my all time high weight. Well, that was then---NOW I'm at my all time highest weight and it is not pretty. I never thought I would weigh this much!! Anywhoo, she sent me for xrays and then to orthopedist. Loved the ortho--kind, caring, knowledgeable, patient. Great guy!! Bottom line: I have no significant damage from the fall but it exacerbated some osteoarthritis in that knee that is fairly significant. Xrays weren't pretty but he was calm. We had the weight talk--I cried, he comforted. Then I had a cortisone shot and got a knee brace for when I start walking again. Right now, I am being sent to our recumbent bike in our dungeon of a basement for daily workouts until my thighs are stronger and I start to lose some weight. He kept mentioning 20 pounds but "that's not set in stone". Seeing as how I've only gained since SP I am not very confident of losing 2 pounds; let alone 20!!! I have to overcome that attitude and pump some positive in my head: I will lose weight this time! I am different than I was and I can do this. HMMM......may need to repeat that quite often!
Just in a bit of a funk today/tonight. I know I'm 63 but feel too young to be dealing with arthritic knee! I do not like aging!! I hate it that I've gained all this weight. So, the two things I struggle with most (aging and weight) were the focus of my day!
I'll feel better tomorrow. Thanks for reading.
