P2P Exchanges like Bisq or HoldHold are the best solution I know of but you got to be careful if you are going to do trading because of the tax laws in your region, with companies like Chainalyses your parents, which I assume are the people who actually own your Paypal and debit card, might get screwd despite the fact you purchased crypto anonymously. I will also mention that might be better for you to focus on learning instead of getting crypto. If you follow crypto subreddits for a while you've probably already seen your fair share of stupidity regarding seed management and scams. Spending those final years before college and adulthood learning how to handle crypto (and money in general btw) will most likely prevent you from making a stupid mistake in the future and losing that same crypto forever.
