Welcome back Angela!
I'm just coming back myself after a long time away. I only lost 15 pounds (175-160), but I'm trying to lose the last 30 to get me to a healthy BMI.
The one thing I can say is - DON'T GIVE UP! Remember how many times the scale just seemed to stop for weeks at a time, and then all of a sudden - 2 or 3 pound drop? This happens with persistence.
I'm so glad you are back and you have a good group here to support you. I think upping the calories was a good idea. Maybe up the calories and teensy bit more, take a day or two off exercise and then go back at it. Your body might just need a rest. You can do it.
