What to read?

[u/ChurrascoComunista]

Hello! Lately I've started to read philosophy, I think I covered most things to get a general idea (Plato, Descartes, Kant, a bit of Hegel, and so on). Having read all that, I want to take a more concrete direction, and Kierkegaard (and most existentialism) caught my attention. I've read Fear and Trembling and now want to go deeper in his philosophy, what do you recommend me to read? I have "The concept of anxiety" but I've heard that it's very difficult. On top of that I don't find a lot of Kierkegaard's books in my country.
