My weight is bringing me down

Hi guys!

I’m 19 and I weigh 13st 3lbs and I’m 5ft 7inch. 3 years ago I weighed 9stone and I was at my happiest and I also got with my boyfriend then too. He thinks I’m amazing a beautiful but all I see is a fat slob, I have no motivation and struggle with what to eat as I’m really fussy.

I really need some help, I want to be back down to at least 10stone by this time next year.

PLEASE HELP ME😓
