Not everyone who criticizes you wishes well for you. Don’t let people influence your mind and control your life.
Change if you have to change, but never because you don’t fit the image someone else outlined for you or because they aren’t happy with who you are.
Allah created you to worship Him and to better yourself for His Sake. Everyone else and everything else is secondary.
وَلَقَدْ نَعْلَمُ أَنَّكَ يَضِيقُ صَدْرُكَ بِمَا يَقُولُونَ
فَسَبِّحْ بِحَمْدِ رَبِّكَ وَكُن مِّنَ السَّاجِدِينَ
وَاعْبُدْ رَبَّكَ حَتَّى يَأْتِيَكَ الْيَقِينُ
Indeed, We know that your breast is straitened at what they say.
So glorify the praises of your Lord and be of those who prostrate themselves (to Him).
And worship your Lord until there comes unto you the certainty (i.e. death).
Surah al Hijr- Ending
