How do I stop peeling?

I went to Costa Rica on vacation a few weeks ago and in 1 day got a complete body sunburn. I’m half black so this whole sunburn thing is new to me, but my skin never got red so I didn’t worry about it at the time. But for a week now my whole body has continued to shed. I know it’s normal to peel but my arms took a whole week to stop and now my legs are starting to do it. I tried exfoliating and using tons of lotion but I just want them to stop!! Obviously picking it all off would take me forever but I don’t know what to do.. Should I just leave it alone or can I do something to stop/finish my skin from falling off?!
