I thought my scars were going away..im so upset

and once again…I think I’ve cracked…my dad is always commenting on my face T_T…I hate it so much..just 2 mins ago hes like..did you press your pimples how come your face got liek the black black stuff..its not black or anything..its just some scars..the ones on my right face is getting better..and I actually thought..”wow its getting better”…and I could feel my self esteem rising abit..and because of him..it just hit rock bottom again..hes so mean…he always comments on it eventhough he knows im sensitive with it… and I really cant take it..I got 2 sisters and their face is almost flawless..no pimple or scar or whatever..the complete opposite of mine!…and sometimes my sis would poke my other sis face for fun…and then she’ll go “ow my pimple!” and im like thinking..wtf you dont even have anything on your face..what pimple!?” and sometimes my other sis would be like..(while looking in the mirror)”omg…ah..its so hot! im getting so many pimples..omg! look at my face” wth man..she only got like..2 pimples on her face and shes like stressing out saying her face is so horrible…how about mine then!? mine is like 10 times worse than hers..gosh..I feel so sad..I eat so much fruits everyday…face my face twice aday..keep it oil free…make sure that none of my hair is falling on my face…and when I sleep I try not to face on any of my sides which could irritate them..im so careful with it ..yet im tortured with these pimples…does god hate my or something..im so gentle and careful with my face unlike other people and yet my face is so horrible..theres this girl in school that said she washes her face with only water..she doesnt have any facial or whatever..and her face is soo smoooth and pimple free…not a single scar or spot…I feel so upset..so depressed..and I cant go to a dermatologist because its too expensive..none of the creams I use hardly work..what should I do…I dun know what I should do..it sso unfair..why is it only happening to me..why is everyone elses face so nice and pimple free even when they dont take care of it that well…even when I take care of mine so carefully I still get pimples.. ;(…its so unfair…and my dad keeps on bringing down my self esteem everytime he mentions bout my face..
