SOPHIA Strahan has promoted her twin sister Isabella’s optimistic mind on social media, subtly reminding everyone to remain positive.

The Strahan sisters are the daughters of Good Morning America star and retired NFL player Michael Strahan.

Sophia, 19, recently shared a quote from her identical sibling on her Instagram Stories timeline.

Against a black background was a paragraph of text that said: “6 months from now, you will be in a completely different space mentally, spiritually, and financially.

“Keep working and believing in yourself.”

In the corner of the Duke University student’s Story slide, it read: “Inspiration via @isabellastrahan.”

Isabella’s ability to maintain a positive outlook on life amid her current health struggles is truly awe-inspiring.

Isabella revealed to the world last month that she was diagnosed with medulloblastoma, a rare condition that accounts for about 20 percent of all childhood brain tumors.

The University of Southern California student hasn’t let her health issues rule her life.

Earlier this month, Isabella released a YouTube vlog featuring her engaging in her workout routine, which included doing sit-ups and exercising on a treadmill.

Explained in the video’s big block subtitles was that the aspiring supermodel had been “focusing on staying strong and healthy” since she was finishing “radiation treatment.”

She was also spending some quality time with “friends and family” before she had to undergo chemotherapy.

SUPPORT FROM FANS

Fans encouraged Isabella in the YouTube comment section, and praised her for pushing forward.

“You are looking so radiant and beautiful. Stay strong mentally! I just finished radiation 6 months ago. You are in my prayers,” one fan typed.

Another added: “Isabella I love seeing this. Sending continuous love and healing vibes to you each and every day of your journey. You got this beautiful.”

Someone else cheered: “Glad to see you’re doing well, despite what you are going through. Keep things strong.”

KEEPING STRONG

Isabella was diagnosed with medulloblastoma in late October and had emergency surgery to remove a golfball-sized mass in her brain.

The teenager and her famous dad, Michael, sat down for a tearful interview with his co-anchor Robin Roberts, 63, on GMA in mid-January.

Isabella burst out crying as she talked about how rare her condition is.

Michael immediately handed her a tissue and put a supportive hand on her leg as she sobbed, “I told myself I wasn’t going to cry!”

He added soothingly, “It happens. You’re allowed to cry,” and Robin added, “Take your time.”

Isabella wiped away tears as she went on, “It’s been like, two months of keeping it quiet, which is definitely difficult.

“I don’t wanna hide it anymore ’cause it’s hard to always keep in. I hope to just kind of be a voice, and be [someone] who people, maybe [those who] are going through chemotherapy or radiation can look at.”

The diagnosis came several weeks after she began experiencing headaches at the start of her freshman year at USC.

Michael took a weeks-long break from hosting GMA at the time, citing “personal family matters.”

“I didn’t notice anything was off till probably like October 1,” Isabella said.”That’s when I definitely noticed headaches, nausea, couldn’t walk straight.
