Ex-NBA star LaMarcus Aldridge says he's struggling in his post-basketball life ... admitting he's been depressed since abruptly retiring due to a health condition.
Remember, 35-year-old Aldridge walked away from the sport back in April ... after a health scare involving his heart following a game against the L.A. Lakers.
As it turns out, the 7-time All-Star played his entire 15-year career with Wolff-Parkinson-White syndrome, which causes a rapid heartbeat.
Aldridge says he learned about the condition back in 2006 but was able to play a decade and a half without any major issues.
