Stretch marks

Im currently 28 weeks pregnant with twins and I have stretch marks really bad. Im so scared that they wont go away after I have the babies. I want to ask anyone who has had stretch marks like this, if yours went away/ went back to normal? Ive always had body image issues and my belly has always been my biggest struggle and I know I will hate my body after the babies come. Im trying to mentally prepare myself for what my body will look like.
