Jaime Alguersuari has worked with "several psychologists" to help him to deal with the "trauma" he feels from his time as part of the Red Bull driver development programme.
The Spaniard made his Formula 1 debut with the sister Toro Rosso team, at the time becoming the sport's youngest ever racer. His career lasted for two-and-a-half years, during which time he started 46 Grands Prix before being cut loose along with Sebastien Buemi at the end of the 2011 campaign.
After a short stint in Formula E, Alguersuari gave up racing altogether and is now a music DJ, under the pseudonym 'Squire'. But in a new interview with Spanish newspaper El Confidencial, he revealed that he is still haunted by the intense training regime overseen by team adviser Dr Helmut Marko.
