Had been absent.

Is it correct to use had been absent to mean I was absent for longtime in past and now I am back. I am providing context below.

"You are aware of my illness owing to which I had been absent for longtime."

Is it correct to use 'had been absent' to mean I was absent for a long time in ​the past and now I am back. I am providing context below.

"[STRIKE]You are aware of my illness owing to which I had been absent for longtime[/STRIKE]."

'You are aware that I have been absent for a long time owing to illness.'
