Suarez left the Camp Nou this summer, after new Barca manager, Ronald Koeman told him to find a new club.
The Uruguay international eventually joined their La Liga rivals in a €5m deal and has enjoyed a strong start to life at the Wanda Metropolitano.
“It was not just an angry and impulsive situation. I was sad and hurt by how things ended,” Suarez told Marca.
“I have already said it, they closed the door on me and I had five giants open to me, that valued my work, professionalism and career.
“I feel proud with what I achieved at Barcelona. I found happiness and I am enjoying this moment now.”
The 33-year-old has rediscovered his goal scoring form, netting five goals in five LaLiga starts so far.
Simeone is likely to be in action when Atletico host Barca on November 21.
