Stop compulsive thoughts and worrying

My biggest is ruminating, i talk and talk and over share with myself and others Like what are some exposures?

Please help anyone else here with Religious ocd and is a Christian? My brain is going hay-wire and want to know I'm not alone... what do your thoughts say and how do you overcome compulsions? Im going through a rough moment and feel sick with anxiety and stiff. I want to obey God but my thoughts won't stop. I surrender to the Lord and then I have peace with the compulsions and they go away but the thoughts are the scary part please - is this spiritual or is it mental? Or is it both? Would love to hear a Christians opinion on this... because my thoughts latch on and won't dissappear but I know that the Bible commands us to take control of our thoughts and to renew our minds...yet God has grace for this and mercy for our every need... I know God is in control (completely) and my mind creates a lot of the issues for me without any spiritual stuff (it's a very powerful thing) but it's still scary. Lord help me, I surrender myself to you Jesus, counsel my soul and help me.

I CAN'T STOP THOUGHTS. I think about meaning of life, time, afterlife and other shit. I can't stop thinking. I cannot distract myself. When my thoughts are the worst I'm thinking about su*cide, and it scares me because I'm not suicidal and I don't want to die. But what if I do something with myself? Please I want any advice what to do, I can't afford therapy at the moment
