As Hydra said, deconversion is a process where you realize (at your own pace) that there are no god or gods. There are many reasons why someone believes in the supernatural without any evidence. It could be witnessing "miracles", hearing about miracles, good feelings and wishful thinking, some variant of Kalam's cosmological argument, an argument from morality, etc. All of these are reasons contain a logical fallacy. I think you should examine claims about the existence of an Abrahamic God in the same way that you examine the claim that someone just saw (the original) Elvis alive.
You've only thought "what if this is BS". If someone told you that they believe that anfadlkfnsdlkfandf is real and that if you want to live forever and have good luck, then you must sacrifice a healthy cat every few years. Otherwise you will burn in hell forever. Your first reaction shouldn't be "what if this is BS". Your first reaction is that this is BS until evidence supporting these seemingly ludicrous claims is put forward.
So to summarize, there are reasons right now that are preventing you from thinking clearly about your current faith. Once you understand why these reasons are not good enough to accept the extraordinary claims of that faith, then you should be able to reject those claims just like you reject that Mohammed is a prophet, a belief shared by over a billion Muslims around the world.
