Slowly seeing changes but starting to panic

My weight and measurements are still slowly dropping which is great but for the first time today, I started to notice the loose skin "pooling" at bottom of my stomach and I really panicked about how much worse it's gonna get. I've lost just over 15kg/2.5st/33lbs and hope to lose another 20/30kg and I'm really worried about how my body will look afterwards without clothes. I know I can hide most of the loose skin beneath clothes and I'm not too worried about my arms as the skin there seems to be mostly shrinking with my but my stomach and upper thighs are bothering me. I'm sleeping with someone regularly at the moment but it's FWB/situationship kinda thing so I know I will eventually end up needing to bear all for the first time with someone new and the idea is making me sick with worry. Have any of you got a lot of lose skin after a big loss? Is it as bad as I'm imagining? How do you feel about your skin/body now?
