Suggest Treatments For Stress And Rashes With Blisters All Over The Body

I get stress rashes a lot, when i get them, i get rashes on my ankles, wrists, hands, and my vagina swells up, and a rash from my vagina, all the way back and up to the top of my butt crack. how do i prevent these from happening? the vagina swelling and rash happens at the same time as my ankles, this time it was the opposite ankle that developed a huge clear blister, and I got one between my toes also. any help would be appreciated.
