People who are always trapped in sadness and believe that their life will only get better if someone enters or leaves it are mistaken. Happiness does not come from others, it comes from within yourself. You must work on yourself, everything has to be done by you and you only.
Hardships are a reminder to turn back to Allah .An awakening that teaches us that Allah is greater than Everything in our life .Turn to Allah swt and push yourself to be patient ,sooner or later you will see how that same hardship was a blessing...
