What can I do for my hands after years of picking?

Years of picking the skin around my fingernails left me with thick finger tips skin. I was doing so much damage to the cuticle skin it left me with bad wounds after .. years of doing that I learned to manage my anxiety and I stopped picking at the skin but it left me with thick skin to clarify normally people have flat skin mine is raised it's difficult to explain it looks like scarring underneath the skin which caused the skin to look thick/raised. (Please see pictures) What can I do?
