I was hoping for some advice regarding hope and fear of Allah I commited sins which i have fear of and have repented but have no idea if my repentance has been accepted. Now sometimes the thought of my repentance not being accepted makes me feel sad and extremely down. Would it be unwise for me to assume that due to the immense mercy of Allah my repentance has been accepted and i can concentrate on doing good deeds? Also i feel shame advising others to be more islamic. I feel like a hypocrite when i myself commited sins at their age, some of which they would be aware of. Any advice?
