Scared of how my body might look after my weight loss

Hey everyone, I’m 18f and weighed around 103kg in April and now I’m at 84 , I’m so happy with myself , I know I’m pushing myself really hard but I’m afraid that I’ll be dissatisfied with my goal weight which is around 60kg .
I know I’ll have loose skin, stretch marks I already have, not to mention how my chest area might look like I know what matters is loosing the weight , I’ve been much better mentally since my weight loss but lately I’m so anxious and disappointed in myself because I feel like my body will never snap back to how I want it to look , my body has been through a lot and I’m proud of myself and where I am now but I just can’t help but feel stuck knowing there’s almost nothing I can do to fix my body
