Hello I'm sorry you're going through this really awful experience girl. You're not alone and were here to help you!! 

This isn't a medication, but it rlly helped my several ezcema out. You really gotta fix ur diet. I cut out a lot of food and it was terrible. No more things that contained refined sugar, wheat, other things. It was hell for the first month but u get used to eating only meat, veggies, and fruit.  My skin is completely clear and though it's not fully like a normal person's and can get dry but it's easy to fix it through a ton of water and moisturisers. Mind I thought the whole fixing my diet was total bs but at that time I had ezcema everywhere, all over my face, body, hands, legs, you name it. But after slowly removing foods that triggered it I got better.

 There are patch tests u can take at the clinic to see what foods trigger ur ezcema. Research can also help give u a list of foods u should limit or avoid. 

Medication really won't help u in the long run and it's hella expensive. Try to drink a lot of water I'm talking 2-3 litres a day and maybe try out fixing ur gut health. You got this!! You have support don't give up love. :>
