It seems that I am constantly worrying about very useless things from one month but I am unable to stop myself from thinking about these useless obsessions. Main problem is that I have an obsession that some useless repetitive thoughts will never go out of my mind throughout my life as these thoughts come with my religious prayers and I cannot stop myself from prayers. What problem am I facing and what is the solution for it? I googled my problem and concluded that I have anxiety disorder.
