Would you forgive a parent/s for making you who you are ?

i am angry at my mm for making me overweight , shes obese and made me huge portions since i was young , which means i eat alot of food ! and i cannot eat less other wise i get really tired , the only reason my sister isnt the same way is ecause she was sick for a long time and didnt eat AT ALL so she doesnt have the same appitite
