Find someone with recent horse experience, who really knows what they are doing. While your mother may have ridden until she was 18? Sadly that does not always translate into someone knowing what they were doing.
I see this all the time, as I am sure many members on here do. And these are people who have had horses for many many years, and actively ride too. Yet on a skill level? Rank beginners, bad hands, bad handling, bad riding.
Get some lessons, both riding and handling, from someone who can read a horse well, and also has good control over their horses, and that means from ground too.
Be careful is something I also second, horses can and do hurt people every day.
Horses make me a better person.
