Stretch marks

I didn't gain any weight the first two trimesters. Then I somehow gained 50lbs in the third. I made it to 37 weeks with no stretch marks. Once I hit 37 weeks, they started popping up slowly, then they came full force. Since I gained so much so quickly, it completely destroyed my skin. My stretch marks are not limited to my stomach. They are all around my belly button, but also on my sides, on the front of my thighs, and my inner thighs all the the way down to my knee, my boobs. Even some on my butt. Dark purple, huge, multiple stretch marks. I've never seen anything like it and I can't stand to look at my body. My husband hasn't seen me naked since giving birth because I'm scared of what he will think. I was hoping I wouldn't get any stretch marks but I figured if I did, they'd just be on my stomach. I never would've thought they would be in so many other places. Has anyone else experienced this? What has helped you?
