How can one alleviate feelings of loneliness, alienation, and longing for family, especially for one's mother, while working in Saudi Arabia?

We advise you to occupy yourself with the Qur’an and Sunnah, read books of the Seerah and accounts of the predecessors, and program yourself to memorize the Qur’an or some books of the Sunnah if you have already memorized the Qur’an. Maintain prayer in congregation, seek righteous companionship that will aid you in good, be keen on supplicating to Allah during the night vigil (qiyam al-layl), observe voluntary fasting, regularly recite adhkar (remembrances), hasten to perform Umrah or Hajj if feasible, and frequently invoke Allah Almighty with supplications.
