ECZEMA HELP!!!

I have dealt with eczema since I was a baby! I'm 21 now and having a terrible flare up! It's honestly been years since I've had a flare up this bad. I'm miserable!! I can't get it to clear up. It's all over my legs. It's so embarrassing I could cry. I constantly want to keep my legs covered even in front of my SO who I've been with 7 years because I think it's so ugly. My flare up started when I was pregnant. My OB said pregnancy can make skin conditions act up. It was pretty mild when I was pregnant. But once my son was here it was full blown awful. I went to my doctor and they gave me some cream. That didn't work now I'm trying another. And I've honestly tried every over the counter cream ointment everything that says for eczema just about at this point. I have a 3 month old who sleep basically through the night but I can't sleep at night because I want to dig my skin off! It's starting to pop up on my arms and stomach. I truly can't take it anymore. I cut my nails down to nothing but still wake up in the middle of the night scratching myself or I can't sleep because I'm so itchy. I take Benadryl before bed it doesn't help. I put hydrocortisone cream on before bed it only helps for a little bit. This new cream from my doctor doesn't seem to be helping either. I'm losing my mind! I want to hide every inch of my skin because I'm so ashamed
