Yng nghanol dinas Caerdydd, pan oedd eira'n dechrau disgyn ar strydoedd y ddinas, roedd Owain yn eistedd mewn ystafell aros mewn ysbyty prysur.

In the heart of Caerdydd, as snow began to fall on the city's streets, Owain sat in a waiting room in a busy hospital.

Dim ond wythnos cyn y Nadolig oedd hi.

It was just a week before Christmas.

Roedd addurniadau Nadoligaidd syml wedi'u gosod yma a thraw yn yr ysbyty: llusernau lliwgar, planhigion corn carbwl yn 'stafelloedd aros, a cherddoriaeth lawen yn rhwydd o gefndir.

Simple Christmas decorations had been placed here and there in the hospital: colorful lanterns, corn plants in waiting rooms, and cheerful music playing softly in the background.

Roedd Owain wedi gwneud prawf meddygol pwysig yr wythnos flaenorol.

Owain had taken an important medical test the previous week.

Nawr, roedd yn aros yn llawn pryder am y canlyniadau.

Now, he was waiting anxiously for the results.

Roedd ei ben yn llawn o feddyliau beiddgar.

His mind was full of daring thoughts.

Beth fyddai’n digwydd os nad oedd y canlyniadau yn dda?

What would happen if the results were not good?

Byddai hyn yn ysbadr awyrgylch y Nadolig iddo.

It would dampen the Christmas spirit for him.

Wrth ei ochr, roedd Alys, ei ffrind gorau ers blynyddoedd, yn eistedd.

Beside him was Alys, his best friend for years, sitting.

Roeddwn hi’n ceisio tawelu Owain gyda sgyrsiau ysgafn a chwerthin i'w dynnu oddi ar ei bryderon.

She was trying to calm Owain with light conversations and laughter to distract him from his worries.

"Pwy a wŷr, Owain," meddai Alys, "efallai y bydd Santa yn ei gwneud yn iawn i ni eleni."

"Who knows, Owain," said Alys, "maybe Santa will make it right for us this year."

Roedd Owain yn gwybod bod Alys yn gwneud yr hyn a allai i'w helpu.

Owain knew that Alys was doing what she could to help him.

Penderfynodd ymuno â'r ymdrechion i anwybyddu’r dryswch yn ei dychymyg.

He decided to join the efforts to ignore the turmoil in his imagination.

"Mae’n rhaid i mi feddwl ynghylch y funud bresennol," meddai wrth ei hun yn dawel.

"I must think about the present moment," he quietly told himself.

Ceisiodd Owain ddilyn sgwrs Alys am eu cynlluniau ar gyfer y Nadolig.

Owain tried to follow Alys's conversation about their plans for Christmas.

“Beth am fynychu'r farchnad Nadolig ar benwythnos?” Gofynnodd Alys yn llawen, gan wenu.

“How about attending the Christmas market this weekend?” Alys asked cheerfully, smiling.

Yn sydyn, galwyd enw Owain o’r grid.

Suddenly, Owain's name was called from the grid.

Teimlai ei galon yn curo'n gryf wrth iddo godi.

His heart pounded strongly as he stood up.

Alys hefyd yn dal ei anadl, llygad i lygad gyda Owain.

Alys also held her breath, eye to eye with Owain.

Gynted ag yr agorodd drws y meddyg, fe feongofion nhw'n dawel i mewn.

As soon as the doctor opened the door, they obediently stepped in.

Roedd yr ystafell yn dawel ac roedd arogl meddwol yn llenwi'r awyr.

The room was silent, and a medicinal scent filled the air.

"Mr. Owain," dechreuodd y meddyg gyda chyfeillgarwch ei lais, "Mae gen i newyddion da.

"Mr. Owain," the doctor began with friendliness in his voice, "I have good news.

Mae eich canlyniadau yn normal."

Your results are normal."

Dilynai tawelwch fel y daeth rhyddhad ar Owain.

Silence followed as relief came over Owain.

Cymerodd anadl ddofn, gan deimlo llwyth enfawr yn llithro i ffwrdd o'i ysgwyddau.

He took a deep breath, feeling a huge weight slide off his shoulders.

Edrychodd ar Alys a wnaeth ei llygad ddisgleirio'r llawenydd.

He looked at Alys, whose eyes sparkled with joy.

Pan roeddent yn gadael yr ysbyty, roedd hei mewn awyrgylch newydd.

As they left the hospital, there was a new atmosphere.

Roedd llawer mwy o gân yn fwrlwm eleni.

There were many more songs buzzing this year.

Tynnodd Owain ac Alys eu cotiau'n dyn, ysgubo'r eira oddi arnynt, a chamu ymlaen i'r ddinas feddigedig.

Owain and Alys tightened their coats, brushed the snow off them, and stepped forward into the enchanted city.

Nawr, gyda phryder ei ddwyni, roedd Owain yn barod i fwynhau'r Nadolig gyda ffrindiau, gan werthfawrogi'r gefnogaeth y maen nhw’n ei gynnig.

Now, with his worries behind him, Owain was ready to enjoy Christmas with friends, appreciating the support they offered.

Dysgodd Owain gwerth y foment presennol, hyd yn oed yng nghanol ansicrwydd, a phwysigrwydd cyfeillgarwch llachar.

Owain learned the value of the present moment, even amidst uncertainty, and the importance of bright friendship.

"Rydyn ni wedi ymosod teliad y Nadolig hwn," meddai Owain, gyda chwerthin yn ei lygaid.

"We've taken back this Christmas," Owain said, laughter in his eyes.

Ac oddi yno, cerddon nhw trwy’r eira, parod i weddu a gaeaf'r Nadolig gorau.

And from there, they walked through the snow, ready to embrace a winter of the best Christmas.
