In the past I did acts of shirk and kufr.Then this year I decided to learn more about islam and aqidah. I found out that some of my actions lead to kufr and shirk. I am so angry at myself and despaired. I made tauba but I am so scared that Allah subhanahu wa ta'ala does not forgive me. I have this feeling that I never would be forgiven. is this only waswasah or am I a hopeless case?
"(And remember that) Allah's acceptance of repentance is only for those who commit evil out of ignorance and then soon repent. It is towards such persons that Allah turns graciously. Allah is All-Knowing, All-Wise." (Sura Nisa 4:17)
