« That girl ! » is def not me

Do other ppl get that sad that they are not « that girl » like i cannot stick to a diet to save my life, i barely work out, i eat junk or nothing at all like, :( i wanna be that girl too, urg. Ive tried so many sport and never get the motivation to just…well do it ? Idk if im asking for advice or venting, maybe both to be honest (But it did work with the food post so why not, share it again)
