I rarely see weight loss results from people in their early twenties and it’s messing with my head

I’m twenty and currently losing weight. I still have about 30 kg to go. I’ve already lost 20 kg, 120 to 100. I don’t really have loose skin anywhere else yet, but my boobs have completely sagged. They’re still round, but they are down. And that has really scared me about what the rest of my body will look like. I also have a massive apron belly… I’ve thought about surgery, but my mom says I’ll be fine if I stick to the gym and build muscle. I get it, we probably can’t afford surgery, but it’s hard not to wish I could just fix it immediately instead of waiting for my body to tighten naturally. When I try to look up loose skin after weight loss, I mostly see much older people with massive amounts of loose skin. I know age plays a big role in skin elasticity, but seeing that makes me worry even more. If you lost a significant amount of weight in your early twenties, what was your experience? Did your skin tighten over time? Was it as bad as you imagined? I’m proud of losing 20 kg. I just feel anxious about what the final result will look like and whether the gym will really be enough.
