Singer KZ Tandingan is one proud daughter.

On social media, she couldn't help but penned a long post to congratulate her mom, who passed the recent Nurse Licensure Examination.

She stated: "At the age of 18, my mother obtained her license as a midwife, and shortly after that, she was appointed a Clinical Instructor. When mum fell in love, married my dad, and had my sister and I one year and nine months apart, her profession was flourishing and she had a future planned. She attempted to balance being a mom and working, but in the end she made the decision to abandon the career she had fought so hard to achieve in order to concentrate on caring for her children."

According to KZ, when she and her sister were in high school, their mom opted to seek a new bachelor's degree and chose nursing as course, but they learned that she was pregnant with their brother after the first year of the four-year program.

And because of the pregnancy, their mother had to transfer to a university that was primarily established for "second coursers," or working people looking to get a new degree with flexible class schedules.

"For a few months, she would do it, but eventually she would put it on hold in order to concentrate on her health and to prepare for the impending birth of our brother," she continued. "When I finally went to college, my brother had already turned three yrs old, Mum continued her education attending classes on weekends till she received her diploma."

KZ then revealed that at 40, her mom tried taking the exam without a proper review because there was just too much on her plate, and sadly she didn’t pass.

"She was so heartbroken that she thought maybe she’s too old or that she didn’t have what it took anymore," she related.

However, fast forward to 2022, at 56 yrs old, more than ten years after she took the exam for the first time, KZ proudly noted how her mom mustered all the courage to try and take it again for the last time.

"She confined herself to her and my dad’s bedroom for almost six months and reviewed for the exam in secret. Only the family knew abt it because she didn’t want people to be disappointed just in case she didn’t pass it again. She would study so hard that she’d fall asleep while reading her books and sometimes forget to take a break to eat," she said.

"The exam dates came, and on the last day, she burst out in tears of worry and joy and collapsed in my dad's arms. She was worried that she might not get the result she’s been praying for but was joyful that even at 56, she was still able to do it."

KZ ended her Nov. 30 post: "Today, 18 days after, the results came out, and I’m so proud to share that my mom, 56 yrs old, MARITES LOBRIGAS TANDINGAN is now a REGISTERED NURSE."

She sent this message to her mother: "Mommy, I can’t thank you enough for loving us so much that you sacrificed your career just to make sure we had the best future. Today, is a reminder that God sees everything and that He rewards His children in His perfect time. Congratulations Mommy Tess! I’m so proud of you. I love you."
