Do you guys think the fandom will die after s3?

Due to mental health problems, I haven't been able to post about Good Omens in the last 3 years because of motivation and it's really upset me. I love the fandom and the show so much and now that I'm finally feeling good enough, I'm terrified I'll only be here for the end. I know the fandom is in it's 30s, but I still have that lingering anxiety.
