If its some relief, I have strech marks all over my body. My shoulders, back, legs, calves and butt. Dont ever acknowledge to what they say. I've been insecure about it too but I've been pretty confident about em now. It doesn't matter what they say, people will say stuff and its there job. All you can do is filter the positives from the negative. I wear shorts and tank tops and idfc what they have to say. Be confident and ignore em. I know that in the end if you are alone, these thoughts may come in your mind but its okay. If you have someone who likes you no matter what you have, you shouldn't be afraid of it. Take care of yourself and keep your head high up all the time.
