Knowledge destroys these bad feelings that are inflicted by Satan. Study hard your deen and be a practicing Muslim.Fearing Allah is part of your inner peace! Without fearing Allah, one is not a Muslim! However, this fear must be positive and making you more productive rather than passive and anxious. Also, perform ruqyah on yourself and you will feel better in a few days, in sha Allah.
