Hi Pleschette! Welcome to the forum. Us girl bassists are few and far between
You're never too old to learn something, as long as you love it. I started playing bass less than a year ago at the grand old age of 27... played guitar for years but didn't enjoy it so learned nothing as a result!
I'm a better bassist already than I ever was a guitarist lol
Keep at the scales and progressions etc, it will all start to sink in eventually. I don't really understand them myself yet but I'm starting to get to grips with the notes on the fretboard, something that was totally lost on me for years on the guitar

(no, not because there are more strings!)
I would suggest getting a good teacher to help with the scales and improvisation, I have a great teacher called Ant, I've improved no end since starting lessons and the encouragement I get from him is priceless.
Anyway, enough of my waffling, I hope to see you around here in the future
