I think the conjunctions 'because' and 'so' are not natural and coherent. Could you help me check it and make it more natural? Thank you.
Because my roommate was ill, I should take her to the hospital. So I forgot it.

The whole statement is unnatural. Can you explain what you're trying to say in a different way?

Assuming your listener knows what "it" is, this is okay.
