Is questioning reality and consciousness a sign of OCD or mental decline?

Does anyone suffer from Schiz OCD. Where you obsess about possibly being schizo

Hi everyone, I think I’ve struggled with OCD since I was a child but it’s seriously effecting my life now. I think I have what you would call Philosophical/ Existential OCD. I can’t stop questioning my reality, the truth of reality and the universe, enlightenment, Christianity, solipsism, god, myself, my own existence. It never ends. I don’t really know what to do anymore. I think I have Pure O, but I also compulsively google my questions and search through the answers for hours until I feel calm. The peace lasts all of 5 minutes and then I’m googling another question. It’s so stupid because I know the meaning of life isn’t found on the internet but I can’t handle it all on my own in my head.

For the past week-ish I have been having a really scary existential crisis that feels like it is stemming from ocd. It started with me being freaking out that i’m going to die one day, then it merge into me being freaked out about what was going to happen after I die (mostly the thought of nothingness). I found some very brief relief in some spiritual beliefs and watching psychic medium readings but then I started think about even bigger and harder to answer questions such as, “if there is a God, who created God?”, “Is the afterlife scary?”, “Could the afterlife end one day?” “What is the point of anything at all?”, “Will the sun exploding destroy whatever afterlife exist?” Really ridiculous questions. I truly believe that there is something after death and something that exists as a life force science cannot explain, but the fact that my mind can’t comprehend or figure it out is really really scary. I feel as if I am going crazy. I have been thinking about nothing but the universe and the meaning behind it all and where it all came from. I can’t enjoy anything anymore. I just want to lay in bed all day and even that is hard. I have been non-stop watching videos about people’s beliefs about this topic trying desperately to find some sort of answer and I am starting to think that may be a compulsion. I am trying my best to remind myself that I when I die I will have all the answers to these questions and I don’t need to worry about this right now because it truly doesn’t affect anything or change anything in my life but it is really hard. I feel as if I have “uncovered” something and my life will never return to normal again. I am terrified that I am going to go crazy or start having hallucinations and that I’ve ruined my life by researching into something so complex and not understandable at all. Any kind of suggestions or anything would be helpful, I hate dealing with this and feeling so crazy and hopeless.
