You must realize the power of your own heart before you hand it over to someone else.
The strength of your heart comes with the worship of Allah, not by constantly being surrounded by people. Spend time in seclusion and see if your heart is at ease.
If you find yourself sad then know that your heart is in need of polishing.
Hearts are polished with the remembrance of Allah alone. Prophet Muhammad ﷺ said: “For everything there is a polish, and the polish of the hearts is in the remembrance of Allah.”
