Roedd y swyddfa yn llawn o syniadau.

The office was full of ideas.

Roedd yr haul yn tywynnu trwy ffenestri mawr, llawn lliwiau'r hydref.

The sun was shining through large windows, filled with the colors of autumn.

Roedd Cerys yn eistedd wrth ei desg, yn edrych dros y cynlluniau lansio ar gyfer eu ap newydd.

Cerys was sitting at her desk, looking over the launch plans for their new app.

Roedd y synau o dipian allweddi a sibrydion cyffrous yn llenwi'r ystafell.

The sounds of tapping keys and excited whispers filled the room.

Ond nad oedd popeth mor wych ag yr ymddangosai.

But not everything was as great as it seemed.

Roedd gwrid coch ar wyneb Cerys - nid yn unig oherwydd y syniad busnes newydd, ond oherwydd pryder cudd na allai rannu ag unrhyw un.

There was a red blush on Cerys's face — not only because of the new business idea, but because of a hidden anxiety she couldn't share with anyone.

Gwyn, ei ffrind gorau a datblygwr meddalwedd brwdfrydig, edrychodd ar Cerys o'i gornel ei hun.

Gwyn, her best friend and an enthusiastic software developer, looked over at Cerys from his own corner.

Roedd wedi sylwi ar y blerwed ar ei gwegil, a diffyg egni yn ei throedigaith.

He had noticed the paleness in her cheeks and the lack of energy in her movements.

Roedd yn amau bod rhywbeth o'i le.

He suspected something was wrong.

“Cerys, ti’n iawn?

"Cerys, are you alright?"

” gofynnodd Gwyn, yn ceisio swn yn anffurfiol.

Gwyn asked, trying to sound casual.

“Ydw, dim ond wedi fy llethu gan y gwaith,” ymatebodd hi gyda gwên wan.

"Yes, I'm just overwhelmed with work," she responded with a faint smile.

Ond nid oedd Gwyn yn dwp.

But Gwyn wasn't fooled.

Gwelodd yr effaith a oedd y straen yn ei gymryd arni.

He saw the toll the stress was taking on her.

Gwyddai bod y presennol lan gerllaw, a bod Cerys yn ceisio ymdopi ar ei phen ei hun.

He knew the presentation was near, and that Cerys was trying to cope by herself.

Y diwrnod cyn y cyflwyniad mawr, roedd Cerys yn poeni fwyaf.

The day before the big presentation, Cerys was at her most worried.

Roedd ei phapurau wedi’u lledaenu ar ei desg, a’i llygaid yn caeadau.

Her papers were spread across her desk, and her eyes were heavy.

Roedd ei chorff yn dechrau gwrthryfela – pen tost, a diffyg ffocws.

Her body was starting to rebel — headaches and a lack of focus.

Ond roedd yn benderfynol o beidio siomi ei thîm nac orffen gyda unrhyw gyfaddawd.

But she was determined not to disappoint her team or settle for anything less.

Y diwrnod mawr, wrth i'r ffeinal ymgynnull, sylweddolodd Cerys ei bod hi wedi rhoi gormod o straen arni hi'n hun.

On the big day, as the final gathering began, Cerys realized she had put too much strain on herself.

Collodd ymwybyddiaeth.

She lost consciousness.

Roedd Gwyn wrth ei gwynt.

Gwyn was right by her side.

Pan ddaeth hi ati hi’n ffwrdd, roedd Gwyn wedi meddiannu'r llwyfan.

When she came to, Gwyn had taken the stage.

Roedd yn arwain y tîm fel pe bai wedi paratoi am yr eiliad ar hyd ei fywyd.

He was leading the team as if he had prepared for this moment all his life.

Gwelodd pobl pa mor hynod oedd y cynnyrch, ond hefyd pa mor ystyriol oedd Gwyn.

People saw not only how remarkable the product was but also how considerate Gwyn was.

Ar ôl y cyflwyniad, gyda Cerys dal yn adfer, roedd rhaid iddi wynebu gwirionedd.

After the presentation, with Cerys still recovering, she had to face the truth.

Roedd Gwyn eisoes yno, gyda gwên garedig.

Gwyn was already there, with a kind smile.

“Rydw i’n gwybod am dy gyflwr, Cerys.

"I know about your condition, Cerys.

Rydw i yma i dy helpu.

I'm here to help you.

Ni fydd rhaid i ti wneud hyn ar ben dy hun.

You won’t have to do this alone."

”Dechreuodd Cerys bledio ei bod wedi bod yn ffôl wrth geisio cuddio ei chyflwr.

Cerys began to acknowledge that she had been foolish in trying to hide her condition.

Fel hynny, gwnaeth hi benderfyniad newydd.

With that, she made a new decision.

Byddai hi o hyn ymlaen yn rhannu’r baich, yn darganfod cryfder mewn help ac mewn ffrindiau.

From then on, she would share the burden, finding strength in help and in friends.

Ac felly, gyda gwên ddewr a theimlad newydd o ryddhad, gwnaeth hi benderfynu wynebu'r dyfodol gyda thîm a oedd yn unedig ac yn barod i ddal ei gilydd i fyny.

And so, with a brave smile and a new feeling of relief, she decided to face the future with a team that was united and ready to support each other.

Roedd eu ap hefyd yn barod i goncro’r byd, gydag ymdrech ar y cyd a chalon agored.

Their app was also ready to conquer the world, with joint effort and open hearts.
