For me, goal weights are arbitrary numbers. Do you have other ways to evaluate your progress? Behavior? Clothing size? Ability to do things? I don't know what, but something other or in addition to the number on the scale. Because you are wonderful no matter what it says.
Everyone should have a "secondary goal" rather than just what the scale says. Mine is to fit in size 10 jeans. (I originally was a 24w, so that is a big difference!)
Also, sleevers can continue losing for 18 months, so keep to your program and you'll get there!
