Jennifer Aniston paid tribute to her "Friends" co-star Matthew Perry nearly three weeks after his sudden death. 

"Oh boy this one has cut deep... Having to say goodbye to our Matty has been an insane wave of emotions that I’ve never experienced before," Aniston wrote Wednesday on Instagram. "We all experience loss at some point in our lives. Loss of life or loss of love. Being able to really SIT in this grief allows you to feel the moments of joy and gratitude for having loved someone that deep. And we loved him deeply."

Aniston continued, "In the last couple weeks, I’ve been pouring over our texts to one another. Laughing and crying then laughing again. I’ll keep them forever and ever. I found one text that he sent me out of nowhere one day. It says it all."

David Schwimmer, who starred as Ross" in the 90s sitcom, also shared his gratitude for Perry.

"I will never forget your impeccable comic timing and delivery. You could take a straight line of dialogue and bend it to your will, resulting in something so entirely original and unexpectedly funny it still astonishes," he wrote. "And you had heart. Which you were generous with, and shared with us, so we could create a family out of six strangers."

Perry died Oct. 28 from an apparent drowning at his California home, law enforcement sources previously confirmed to Fox News Digital. He was 54.
