The problem is I've never been thin
I (22F) went from 180 to 128 pounds over the past 9 months. I'm 5ft1 and I've realized that part of the reason I've become unmotivated while still constantly dwelling on whether or not I'm making progress is because I have no idea what my goal should be.
I just saw a picture of myself when I was 11 and I was clearly very obese. I've always weighed so much than is healthy that I have no idea what a thin version of myself looks like so I have no idea how long I still have to go before I feel happy with my body. Do I just need to lose 5 pounds? 10? 20? 30? I have no clue and its really sad that I have never been at anything remotely resembling a healthy weight since I was a very young child.
Its also become so much harder to lose each additional pound and I'm going to be starting grad school in a few months which means I will have a lot less time and energy to focus on weight loss.
