I have practised hema for years and own a few swords, knives, and a crossbow that I practice with regularly
My advice would be to learn to fight, armed or unarmed martial arts will always be useful

Edit: also to add, if the only fights you have ever been in are schoolkid scuffles or drunk brawls, then you NEED to spar with actual people, getting used to being hit hard is very important. You will be of no use to anyone if you can throw the most beautiful right hook in the world but crumple into a ball when someone hits you back
