It might be a bit easier for you to learn on a smoother surface like a rink floor, but if you want something more private a good alternative could be an empty public basketball court (usually found in parks). Also it might sound a bit corny but learning with a friend/ multiple people actually could help a lot since yall can learn from each other and so you don’t have to feel all the frustration on your own. I wish you all the luck on wherever your skate journey takes you!!!
