im 16 years old, i've been wanting to lose weight nearly all my life, i think i was only skinny till i was 5 years old lol. i cant remember myself buying clothes that actually fit

. i've tried herbal life. which actually made me lose weight at first and then gain it all back and more. i feel depressed from the way i look, its not only because im fat but a milion other stuff [like stretch marks, and having exesive hair growth in ereas i know it sounds disgusting]
im 185 lbs/84 kilos
and only 5"2' / 158 tall
i look like a human penguin hah. thats actually how people tease me.
i really want to be 114 lbs-123lbs/52-56 kilos.
but i dont know where to start.
theres a
chance my family's gonna move to a diffirent COUNTRY. and i was thinking i really need to lose weight before that. so i can meet up with my longtime crush that ive been talking to for 2 years on the internet[met him through a classmate so no chance he's a pedophile heh] because if i dont i dont think ill ever meet him.
and as a fresh start in the new country.
ps: where do you get those sigs that show how much youve lost weight hah they're really neat.
