I’m self conscious

I have stretch marks everywhere. From my shoulders all the way to my calves. I have them on my arms and my sides and my stomach and my thighs and my calves and now they’re stressing down my forearms. I don’t get it! I don’t get it! I’m not even gaining weight rn! I’m losing it at a healthy rate and they still won’t stop appearing! I’m a teenager, it’s not like I have pregnancy to blame it on, But look like I’ve been pregnant by the looks of the stretch marks on my mid section. It doesn’t make sense to me because I have a pretty decent figure and girls bigger than me don’t have them so why is it plaguing me?? Does anyone know what I can do to stop them? Because looking in the mirror this morning made me depressed. I feel helpless and hideous. No guy would want to be with me. ever.
