completely understand this. I think for me at least it has to do with how I interact in groups. I do not interject myself easily into group conversation and like you, I end up waiting for others to talk about things that I too am interested in, and many times that never happens. I'm sorry I know it's hard. I wish I had a solution other than being in groups where their highest interests are ones I can relate to.

I typically shy away from groups of people IRL because of this.

I'm sorry this isn't advice but I understand completely and empathize.
