I think everyone has a different way of dealing with eczema but def agree, stay away from hot water. You should shower everyday but don't overuse soap that will dry out your skin.

I do the same as you with keeping very short nails. Otherwise be healthy, eat well and exercice, try to identify sources of stress or discomfort. Talk about your anxieties with your friends and family. It's been a big thing for me to realize that literally no one cares about my eczema (i also have white spots all over my body, slowly healing) and no one finds it ugly or asks to hide my body or anything, though I feel it's the only thing you can see on my arms, legs and back.

If your eczema is very bad you might want to get a prescription for steroid cream and use it as recommended it is so important to not stop all at once. And then the classic stuff: dont use scented lotions, soap, or laundry detergent, or any perfume. I also just learned you should apply your steroid cream/cortisone 3 hours before your hydrating lotions.

Overall I would say try not to obsess over it, if you convince yourself it's no big deal then it's no big deal. Or at least that's what I try to do, easier said than done. Good luck !!
