OCD? Anxiety? Feels like my mind is out of control..

Hello everyone. I've been obsessing non-stop, 24/7 about things that don't really have an answer, and it's causing anxiety/obsessive worrying. It started off as a normal day, then I ran across a video that triggered me. It said something about God not being real and the government was using religion as a tool to comfort us, so I began to question, "is he real?" "How do I know he exists?" And it scared me quite a bit, because I have always believed he was real, but when I see things like that, it makes me question it.😞 Another this that has been stressing me out 24/7 is the theory that we live in a simulation and that everything isn't real & I can't seem to shake that thought off either. Any thoughts or opinions on this? Has anyone else been through this too?
