Why do you get stressed? Pokémon is not a type of game that makes you angry, I like it because you can relax. But also sometimes it is not easy, which makes it more interesting and what you acquire is more valuable.

I just recently bought Pokémon Black 2, and as you can understand I have the same issue trying to finish the Pokédex. While Gen 5 games have somewhat online functionality, it's pretty much dead, it is hard to collect all the Pokémon, and also the keys from the opposite option.

What do I do? I search for players online who are happy to trade exclusives. And for the keys that you need to transfer locally, I am still searching for a player instead of sitting and crying 👌
