Constant itchiness "eczema" Suggestions!

I have been diagnosed with eczema since I was a very young child but now I can't help but believe that's not true. I can't sleep at night because I am constantly itching. I have scabs all over my legs torso arms back and neck and even face. The reason I can't believe it's eczema is because I have done literally everything that has been asked o me and continue to see no progress. I have used probably every lotion (non scented of course) you can think of. I have taken baths with chlorine. I have tried taking breaks between showers (every other day) I have had ointment prescribed in tubs (trimacynaclone) and I take pills to try to help not itch (ineffective) it is getting to a point where I will sleep maybe 1 hour in a night combined because I will just jolt up and scratch. My sheets look as if I committed a murder on them because there is dots of blood and dead skin everywhere. Please do help with suggestions
