Assalamu alaikum wa rahmatullahi wa barakatuh I'm a revert, I already have religious trauma from people who claim to be upon salafiyah, I got treated really badly and now all I do is fear my religion, at one point I refused to make any new friends. How can I improve my condition?

Ustadh AbdulAziz al-Haqqan

This is not fear of religion but rather of people who as u explained betrayed you. May Allah give us and pious company. I suggest let seeking knowledge be your companion the quran and sunnah, lessons, book, and the ulama
