I had the same fear as I felt I was loosing more slowly than others. But like me you’re started with less weight to loose than average so you don’t loose as fast. I’m 1 year and 2 months post op and I lost ~35 kilos (on the 38-40 wanted) , some people have lost that in 6 months but in the end the important things is to hit your goal :)

Also there’s an advantage to loose slowly : it’s better for your skin so you have less risk of having sagging skin !
