Zelda Williams is having a tough time getting on without her father, Robin Williams, since his unexpected death in August 2014.

The 25-year-old actress already got a tattoo of a hummingbird on her hand to preserve her father's spirit.

"It's hard to keep them (hummingbirds) in one place, and dad was a bit like that. Keeping a conversation in one moment was impossible with him. It was a bit like trying to put a bag around a storm and hoping it didn't blow away," she said of her ink and her dad's personality.

Though her tattoo serves as a daily reminder of him, she still feels the emptiness and admitted it will require "a lot of work" to have the "fun, happy life" that she previously had, according to USA Today.

Zelda reassured her supporters that she is trying to focus on the quality of her father's life rather than harping on and reliving his death.

"Diseases are, until we find out exactly how they work, we don't have an explanation. So there's no one I can offer ... There's no point in questioning it. There's no point blaming anyone else for it. There's no point blaming yourself or the world or whatever the case may be because it happened. You have to continue to move. You have to continue to live and manage," she explained on "The Today Show" this morning.

She hopes that negative stereotypes surrounding mental illnesses will be eradicated and people will work to understand and treat diseases, Us Weekly reported. "Nothing happens immediately, but I think we're on our way."

One of the most important things that Zelda wants people to remember about her father is that through his comedy, kind nature and wisdom, he made an "enormous amount of people in this world feel less alone."

"Anybody who has ever lost anyone works very hard to continue that memory in a positive way." And that's exactly what she will do.

Six months after her father's suicide, Zelda will honor his memory and humanitarian work by presenting a "Noble Award" at the Challenged Athletes Foundation.

"Laughter was incredibly important to him," she said. "The world keeps spinning, but that doesn't mean he was never on it."

The comedian was 63 at the time of his death.
