Should I tell my religious family I no longer identify as Muslim?

Right now, I don't know what to believe or not believe, but I reject Islam because it shows no respect for me. Maybe I'll change my mind later or decide to follow another religion—I can't say for sure—but the real problem is how to tell my family. They are very religious; what if they disown me or refuse to see me? Ugh.

I want to clarify this point: my head won't be cut off just because I'm not a Muslim; Türkiye is a secular country and is not governed by religion.
