Hi I'm 13 And I Wet The Bed. I Got

Hi I'm 13 and I wet the bed. I got some rash on my skin and it's eczema. It itches a lot and I've never had this before. I don't remember when I got it but I think it was a couple of months ago. Do I have eczema because of bedwetting? I stress a lot about this. Will my bedwetting and eczema ever go away? Thank you. I really need your help since there's nothing really online about what I'm searching for..
