Is it normal i am still bit fearful of the disturbing thoughts from anxiety?

When I went through a really bad stage of anxiety it lead me to a very dark place of depression and black thoughts along with a lot of racing disturbing ones that contributed to the panick attacks that I had constantly. Well thank fully Im recovered from anxiety now and am very happy again. Unfortunately I still remember all those nasty thoughts sometimes that were very very disturbing- I dont react anymore but i just worry a bit and feel bad they are still around- I often think "Oh damit, why cant I just completly forget them"! is it normal that I still wory about them ?
