I'm 100% sure it's because you're not using a pot with good drainage, right?! And the humidity is also wrong. That's why it's angry, LOL. I suggest you water this plant at least once a week and give it indirect sunlight, which also affects why your leaves have brown spots! It could also be due to pests like spider mites and fungus gnats, but don't worry, so many fertilizers are sold to keep plants healthy.
