OK...... so ...I'm thinking that maybe I'm just *TRYING TOO HARD*...? I mean, I KNOW the facts. And these are THE FACTS:
I KNOW I've been eating HEALTHY. I KNOW I haven't gone *astray* with my calories (I record EVERY BITE that goes in my mouth!) and I KNOW I drink plenty of water and I KNOW that swimming for an hour a day & walking a 1/2 hour a day is GOOD exercise. I KNOW that I am taking good vitamins & watching my sodium intake, & eating lean meats & veggies & fruits... and I ditched the junk food & even soda & pretty much all I drink is coffee (2 cups in the a.m. while getting ready for work) and water the rest of the day. Occasionally I have a Diet Dr. Pepper - but that's not everyday & I never have more than one. I am getting plenty of sleep.
I AM IN PERI-MENOPAUSE. (I call it "p-pause".)
The only thing I can think of is that my hormones are really SERIOUSLY kicking my a**.

I am taking vitamins & treating my p-pause naturally because of the pulmonary embolism I had last year, I can never take any kind of hormones ever again. But the natural approach seems to be working for me in that I have NO MORE night sweats, NO MORE hot flashes, and the mood swings are practically non-existent. However - my weight is STILL a problem. Hence "my hormones are kicking my a**" idea.
So yesterday I left work, went home, & got in the pool. Instead of swimming my usual laps & concentrating on my form, I just SWAM. I decided to just CHILL OUT. I swam for RELAXATION, not for "exercise". I listened to the quietness. I paid attention to my heartbeat.
Maybe I do need to just *maintain* for a while. Perhaps, after my surgery, once I'm healed, I can get back to an exercise routine that I know has worked for me in the past.
Until then... I MUST GET OVER THE ANXIETY & ANGER & FRUSTRATION & WORRY about *not* losing weight. I think I may even need to forgive myself & somehow learn to let go of the boot-camp mentality.... STOP focusing on weight loss. Just focus on HEALTHY.
That won't be easy for me; I'm results driven.
Thanks to everyone for their suggestions & support.
