Thiago Silva, 33, joined PSG from AC Milan in 2012 for a reported fee of £37.80m (R645m) and has since won 16 trophies with the French giants.
However, fans and media alike have branded his leadership as a key reason for their shortcomings in the UEFA Champions League - which the Brazil international concedes has taken its toll on his emotions.
"It is impossible not to hear some of the criticism," Silva told ESPN FC. "However, no newspaper, nor journalist, is going to tell me who I am. I know who I am. Because of this, I continue as I always have done.
"I respect all opinions, but when you are attacked personally, it starts to get hard. I am especially sad when it impacts my family and my loved ones. However, when you wear the PSG shirt, you always have a responsibility."
With two-years remaining on his current deal, the veteran centre-back claimed he won't seek to extend his stay.
"I must continue to work hard to help my teammates. Competition always exists in football. All things said, I am 33. I have two years left on my contract and after that, I will hand over to somebody else."
