I havn't bn 2 a dermatologist yet but i'm sure i hav some form of dermatitis?

i've been 2 the GP taken the steroid creams they've prescribed which worked 4 about 3 weeks & thn it came back again. i hav to wait 4 dermatologist appointment in may & since then tried to eliminate stuff from my diet & trying natural remedies but still hav the skin condition but it has changed overtime but not necessarily getting better. i don't know what to do. i hav a feeling stress has a major influence but it's hard to suddenly de-stress... anyone have suggestions/ideas?
