Hello! You are very close to being accurate, but the sentences need a little adjustment:

- Crude oil isn`t only u s e d a s (?) fuel, it also c o m e s a s (?)
pesticide and fertilizer.

U: Crude oil isn't only used as fuel, it's also used in/a component of pesticide and fertilizer.

- Doctors`opinion is (?) that he won`t recover.

U: The doctors' opinion is that he won't recover.

- If your brain doesn`t produce those chemicals enough (??), you will get
depressed.

U: If your brain doesn't produce enough of those chemicals, you will get depressed.

Please let me know if you'd like more explanation.
