I am having the worst panic attack of my life

I have been living in sin and i want to repent and return to God the other day i felt a wave of absolute terror wash over me regarding God’s judgement after i die, i am so scared that i wont make it to the kingdom of heaven, please pray that God would have mercy upon me and guide me to repentance and also that he would send the Holy Spirit to comfort me and guide me into all truth, thank you my name is Jeremy
