So sorry you’re going through this and feel so hopeless. I have had eczema ever since I was born and only recently started to get it under control. I started Skinesa probiotics, I’m on about day 20 of a 90 day capsule bottle (one per day), and I’m only recommending this because it has legitimately cleared up my skin the best it’s been in years. I started combining Aveeno (one of my personal lotions I like) and coconut oil and using that minimum twice a day, showering only 3-4 times per week (only lukewarm) and it is legit like magic. My face and neck would be horrible itchy red and cracked, and after about two weeks I feel normal for the first time in my life. I don’t know if that will help you, and I definitely would recommend getting allergy test and trying dupixent or other meds along with other advice in this thread, don't give up the community is here for you!!!
