Success–Failure–or just Reality

I'm a year and a half post op - I stopped loosing at 13 mos. Which means i have not lost anything in the last 6 mos. (ok since September 23rd. I reached 235 the very next day 240.) For a long time I teetered between 240 and 243 right now its more like 244 to 246.  So am I a success or a failure?
At 235 that had me down 132 pounds. That's pretty great in a year.
But dang it I should of lost more - should of had something to show for the last 6 months. 
Suppose that is just the way it is. I wanted to reach 200 but that was expecting way too much.  
Would of thought that after loosing so much weight that i would be feeling so great.  Honestly, not so much.
I can move more, have more stamina. Oh such a blessing to go grocery shopping and not be so dang winded.  I can tie my shoes in the front vs on the side. I can cross my legs (ok gentlemen style but still couldn't do that before)
But i am still tired all the time.  ALL THE TIME.
Yup, I am a type1 diabetic, I have sleep apnea - still using my machine.  Labs are all normal. (OK for the most part)
Found out a week or so ago that I have lupus, what does that mean to my general health? I haven't a clue to be honest. Still wrapping my brain around it, and waiting to see what a doctor will say - but that won't be for two more months or so.
I'm glad i had the surgery - I never had issues with dumping or vomiting or any other adversities. (early post op I had issues from the incision site because I got the privilege of having an open RNY vs lap) but all in all no real issues.
But I can't help but feel that I have failed at this weight loss attempt.  Sort of like my mind is yeah ok your 100 pounds Plus lighter than you used to be. Life is better in so many ways.  And yet there is still that voice in my brain that keeps sticking it to me, that I'll always be a weight loss failure.
