I used to fall asleep around 10pm but I ccan do that om these days because I have stress out of getting a job. この表現は自然ですか？

ccan should be can't; a contraction combining can and not into one word. Om should be removed. I have stress out of should be I am stressed about.

Overall: "I used to fall asleep around 10pm, but I can't do that these days because I am stressed about getting a job."
