Wrth fynd i mewn i'r ysgol breswyl newydd hwnnw, y teimlad oedd fel dod i fyd newydd sbon i Rhys.

When entering that new boarding school, the feeling for Rhys was like coming into a brand-new world.

Roedd yr ardal yn Snowdonia yn bopeth roedd pawb wedi ei ddweud - trawiadol, serch hynny anghyfarwydd.

The area in Snowdonia was everything everyone had said it would be - striking, yet unfamiliar.

Ar ôl i'w rieni wahanu, teimlai Rhys fel pe bai ei fywyd wedi troi wyneb i waered.

After his parents separated, Rhys felt as if his life had turned upside down.

Roedd o'n hiraethu am ei gartref, ond roedd ei fam a'i dad wedi penderfynu mai yma y byddai'n cael y cyfle gorau i ddechrau eto.

He longed for his home, but his mother and father had decided that here he would get the best chance to start again.

Mae Carys a Emrys, dau disgybl arall yn yr ysgol, yn gwneud eu gorau i wneud i Rhys deimlo'n gartrefol.

Carys and Emrys, two other pupils at the school, did their best to make Rhys feel at home.

"Dewch, Rhys, mae brechdanau cinio'n orau os wyt ti'n dod yn gynnar," meddai Carys yn ddigon llawen.

"Dewch, Rhys, lunch sandwiches are best if you come early," said Carys cheerfully.

Ond roedd Rhys yn fwy awyddus i fod allan, i deimlo awel natur ar ei wyneb nag i fynd i'r cantîn, sy'n golofn o sŵn ac arogleuon.

But Rhys was keener to be outside, to feel nature's breeze on his face rather than going to the canteen, which was a column of noise and smells.

Bob dydd, wrth i'r dail ddisgyn fel eira'n araf ar dir y mynyddoedd, teimlai Rhys y magl o straen y cartref.

Every day, as the leaves fell slowly like snow on the mountain's terrain, Rhys felt the snare of stress from home.

Roedd yr ysgol yn ei rythmau caeth.

The school was in its strict rhythms.

Roedd amser cinio, gwersi, a phob math o reolau yn tynnu ar ei amynedd.

Lunchtime, lessons, and all kinds of rules tested his patience.

Beth bynnag oedd ynddo ef, roedd fel pe bai angen dianc i'r awyr agored.

Whatever was in him, he felt the need to escape to the outdoors.

Un diwrnod, penderfynodd wneud hynny.

One day, he decided to do just that.

Wrth iddi fachlud, Rhys aeth ati i archwilio mynyddoedd creigiog Snowdonia ei hun, heb ddweud wrth neb.

As the sun set, Rhys went to explore the rocky mountains of Snowdonia by himself, without telling anyone.

Y dramorfaenau yn sibrwd straeon o'r gorffennol, tra bod coed derw yn siglo'n synhwyrol yn y gwynt hydrefol.

The ancient stones whispered tales of the past, while oak trees swayed sensibly in the autumn wind.

Roedd y gweundir yn gyfrinachol, yn glo chwyrlïo mewn tlysni tawel.

The moorland was secretive, spinning quietly in serene splendor.

Fe wnaeth hynotaeth Rhys fynd a chyffro.

This adventure took Rhys with excitement.

Ond yn sydyn, cododd awyrgylch annisgwyl.

But suddenly, an unexpected atmosphere arose.

Storm yn naid dros y bryn, gwynt yn rhuo.

A storm leaped over the hill, wind roaring.

Afrosgo roedd o'n ddarganfod ei hun wedi colli.

Awkwardly, he found himself lost.

Tystiodd i'r gwynt a'i ofnau yn gymysg ac yn troelli.

He witnessed the wind and his fears swirling together.

Ddim yn gwybod pa ffordd i droi, roedd poen distaw o ofn yn dechrau drifftio i'w feddwl.

Not knowing which way to turn, a quiet pain of fear began to drift into his mind.

"Dw i'n unig," meddai Rhys wrth ei hun, ond roedd yn gwybod ddim i ildio.

"I'm alone," Rhys said to himself, but he knew not to give up.

Dyna oedd ei benderfyniad, ei wefr dan ei ddwylo wrth iddo ddod o hyd i lwybr yn ôl ysgafn.

That was his decision, his thrill under his hands as he found a light path back.

Pan ddaeth cerdded yn anodd, canolbwyntiodd ar ei anadl ac ar gyffyrddau bach y gwybodaeth - llinellau coed a llwybrau bychain yn seicolegol drwy'r gwynt oer.

When walking became difficult, he focused on his breath and the small touches of knowledge - lines of trees and tiny trails, psychologically through the cold wind.

Roedd y golau yn dechrau pylu wrth iddo ddod o hyd i'r ffordd yn ôl i'r ysgol.

The light began to fade as he found his way back to the school.

Er iddo deimlo'n rhydd ond hefyd wedi dileu ac ar goll, roedd y profiad wedi gadael effaith.

Although he felt free but also erased and lost, the experience had left an impact.

Roedd wedi dod o hyd i rywbeth y tu mewn iddo'i hun.

He had found something inside himself.

Aiff Rhys i gysgu yn yr ysgol honno gyda heddwch anadl newydd.

Rhys went to sleep in that school with a new breath of peace.

Ei annibyniaeth oedd nid yn unig yr hyn a wnaeth o deimlo'n fyw, ond hefyd darganfyddiad mewnol o dawelwch gyda'r cyfuniad o unigrwydd annisgwyl.

His independence was not only what made him feel alive but also an internal discovery of tranquility with the combination of unexpected solitude.

Roedd o dal i deimlo hiraeth, ond dywedasai e wrth Carys ac Emrys, gyda'r wawr newydd, am ei daith ei hun a'i ddewrder - a phawb yn gwenu, fel pe baent yn gwybod taw dim ond dechrau oedd hwnnw.

He still felt longing, but he told Carys and Emrys, with the new dawn, about his own journey and bravery - and everyone smiled, as if they knew this was only the beginning.
