How can the pain of separation from a very close friend be alleviated when one is forced to move to another country to complete studies?

Exaggeration in love and hatred is not commendable, and moderation and balance are in accordance with Islamic law. Therefore, one should be cautious of excessive attachment to a female friend and occupy their time with what benefits them in their religious and worldly affairs. Love should be for the sake of Allah, not for personal gratification. When the heart is filled with the love of Allah and His Messenger, the love for others returns to its proper proportion. The path to loving Allah and His Messenger is through knowing Allah and His names and attributes, reflecting on His blessings, pondering His words, and learning about the Prophet's Sunnah, his life, and his character, as well as frequently remembering death and the Hereafter, and engaging in remembrance (dhikr) and supplication (du'a).
