Loose skin after a lot of weight loss

Hi guys, before i started to loose weight i weighed 17st 8lb, im 5ft 11".



I started to loose weight by cutting down on food, not snacking etc & now weigh roughly 14st. I lost the weight quite rapidly.



I have been left with quite a lot of loose skin on my theighs, upper arm & belly, im finding that this is almost worse (for me) than when I weight my highest & was wondering if anybody knew how I can get rid of this or if it will go away on its own. Im only 17 so still quite young.



Thanks guys!
