While Alicia Vikander may seem like she has it all figured out having starred in blockbuster films, the Swedish-born actress says fame made her feel lonely.

"When, in other people's eyes, I was at my height of fame, I was the most sad," Vikander said in an exclusive interview with The Times. "I kept telling myself, 'Take it in. It is incredible.' But I didn’t know what to do. There were all these first-class flights, and five-star rooms. But I was always by myself."

While others can easily choose to take a break to deal with hardships privately, the 33-year-old actress said the unique nature of her job made it harder to do so.

"Sometimes you go through things that are tough in life and if you have an office job you can step away for a bit. But there are times that myself or colleagues have been through something and, well, I can’t understand how they went on to the red carpet afterward," she added. "To be met by people asking, 'How are you doing?' Given what they had just been through? Most people would not be able to step out of their house."

Vikander, who was in her 20s when she won an Oscar for a supporting role in "The Danish Girl," thanked her friends for helping her deal with the difficulties of her work, especially when she felt "very lonely."

"If I didn't have my friends to call, it would have been difficult. I've seen what can happen to people in my industry," she told the outlet.

This is not the first time Vikander has spoken about the challenges of being an actress. In April, she told Harper's Bazaar that she used to feel uncomfortable filming nude scenes without the presence of intimacy coaches.

"The coaches should have existed at the beginning of my career. I've been in situations that were not fine, where I didn’t feel I was protected," she explained.

Vikander had previously did intimate love scenes on "Tulip Fever" and Netflix's "Earthquake Bird."
