I had a similar problem with my dad and considered quitting magic. What I would recommend, since your mom has seen several of your tricks now, is to find something new and powerful, and practice it more before showing it to ANYBODY.
This past year I performed a full show for my family during vacation. I also built up my playing card collection (now almost 30 decks). This was a fun year, I purchased some new tricks, and overall learned a lot.
In 2019, I hope to learn some new visual magic, film at least one street magic...
