I think about killing myself everyday is it normal?

I think abt killing myself everyday, recently my now ex gf broke up with me and everything has gotten worse. In my mind I tell myself it’s for attention but I’m not telling anyone I want to kill myself so idk how that makes sense. I don’t want my family to suffer but I can’t keep going. I don’t want to tell them abt my thoughts either because I don’t want them to worry. Idk what to do it’s getting bad tho and I’m not sure how much longer I can go on
