Don't worry about your moms opinion for now, I'm sure it's great! :)

I'm sure some people will show up even if your mother won't

You can still use those negatives to develop a portrait.

One photographer to another- Try not to be too hurt by it. I mean yeah it SUCKS but it's how photography is. People pay SO much more attention to other arts and that's just how it is. My own mother got distracted by the painter's booth next to my booth when I did little showing. It's how it is.. :/

Maybe she wants to surprise you?

Keep striving for greatness my dear. If you're already at the point where you feel you're ready to have an exhibit, then you're already lightyears ahead.

That's only the first one OP don't give up on your dreams fight on !

You could always post it on social media, and let people join. Your mom doesn't seem supportive. Good luck, I hope many guests show!

good job. I know you want her to be there but this is about you. be proud that this is your first gallery.

Yu got my support, art is not about having followers, is about expressing yours. and your doing that alrdy
