As salam alaikum warahmatullah wabaraktuhu
Brother i know how u feel i used to feel like that alot but keep praying and Allah (swt) will ease your heart....it is saytan which puts doubts in our hearts and leads us astray.
Allah knows we will make mistakes and sin we are human after all.
<b>Plz dont let saytan win</b>, for your own sake and those around you.
Your in my dua's
salam.
