Just needed to let it out...

Hi brothers & sisters. I hope everyone is well. And I hope you all can offer me advice.

As the heading says, I just need to let out what's bothering me. When I go to church, in my head..it be like taking the lord's name in vain..it's in my head..in my thoughts.

I know it's wrong but what can it be? What is putting these thoughts in my head? I don't want to take the Lord's name in vain. I want to go to church and be contended. I am disabled and I still try my best to go but I just don't understand. I don't want my thoughts to overpower my heart.

I am trying my best. Any advice?
