salaam, I am a 20 year old male and for past 6 or so months I have been suffering with anxiety. It started with a panic attack at school and lead to my diagnosis of GAD (general anxiety disorder) I want to know Islamic views on this mental topic and any help will be appreciated.

Walaikumussalam
Have a strong faith in Allah and His power pray to him with the intercession of Ahlul bait as
Quran is book of Shifa and RAHMAT as quran said
‎وَنُنَزِّلُ مِنَ الْقُرْآنِ مَا هُوَ شِفَاءٌ وَرَحْمَةٌ لِّلْمُؤْمِنِينَ وَلَا يَزِيدُ الظَّالِمِينَ إِلَّا خَسَارًا

And We reveal of the Quran that which is a healing and a mercy to the believers, and it adds only to the perdition of the unjust.
Sura Isra ayah 82
Kindly recite salawat 5 times after fajr then above ayah followed by following ayah 14 times
‎الَّذِينَ آمَنُوا وَتَطْمَئِنُّ قُلُوبُهُم بِذِكْرِ اللَّهِ أَلَا بِذِكْرِ اللَّهِ تَطْمَئِنُّ الْقُلُوبُ

Those who believe and whose hearts are set at rest by the remembrance of Allah; now surely by Allah’s remembrance are the hearts set at rest.
Surah Raad ayah 28
Then once
‎هُوَ الَّذِي أَنزَلَ السَّكِينَةَ فِي قُلُوبِ الْمُؤْمِنِينَ لِيَزْدَادُوا إِيمَانًا مَّعَ إِيمَانِهِمْ وَلِلَّهِ جُنُودُ السَّمَاوَاتِ وَالْأَرْضِ وَكَانَ اللَّهُ عَلِيمًا حَكِيمًا

He it is Who sent down tranquillity into the hearts of the believers that they might have more of faith added to their faith– and Allah’s are the hosts of the heavens and the earth, and Allah is Knowing, Wise–
Sura Fath ayah 4 followed by salawat 5times
Kindly repeat above aamal after isha also
Inshallah you will be fine.
