Is it possible for ocd to become real ?

Is ocd supposed to feel like a genuine belief ? I see or hear some people saying things like « I know it’s not true but …. » while I personally don’t « know that it’s not true » I feels genuinely real and I even find evidence for it

Can ROCD make your thoughts and feelings feel 100% true or real???? Like I can have a thought or feeling and in that moment it feels real or should it not feel real until the ocd latches onto it?

I suffer from religious ocd. My only goal in life is to live in God's will and to serve Him - to live and enjoy His eternal purposes & His presence. Jesus Christ is my life. That is my only desire on this earth, this short trip into eternity, and it's being stripped by ocd thoughts and intrusive thoughts 24-7. I have read many times that ocd can 'feel real', and this is true, our minds lie to us because of fear and anxiety we can't and were never meant to carry. I have begged and tormented myself in every way to find an answer from God. I think His answer may be that this is OCD, but I'm not sure. I started therapy again because I am so exhausted and this had stolen so much of my life in a spiral of negativity, depression, and constant anxiety & intrusive thoughts. I have spent about 2 years trying to figure out if my thoughts are real or not, especially with ocd it can deceive so easily as a spiritual matter when in reality it is just a thought, which is confusing and scary to say the least. Can anyone share their experiences with this sensation? No matter what the theme is... Thank you & Praying for your comfort
