As salam alaikum wa rahmatullahi wa barakatuh أحسن الله إليكم Remorse is a pillar of repentance so how do I know my remorse is enough, is being afraid that what I've done might take me to hellfire enough, what should that fear feel like exactly?

Ustadh AbdulAziz al-Haqqan

Yes, it is enough, and do not dig too deep. Remorse is when you regret something—as simple as that. You don't like it; you don't want it.
