You can get through it and do well by putting in the work as everyone is saying.
However, if you do start to seriously feel very overwhelmed and stressed about the work load, talk to your VCE or year level, or a teacher you're comfortable talking with. Don't try to cope with it if you absolutely feel like you can't.
I originally had Visual Communication Design as part of my VCE lineup for year 12, but at the end of unit 3, withdrew internally from the subject after much deliberation with multiple levels and kinds of staff due to the stress starting to damage my physical and mental health. Withdrawing internally meant I was not in the subject in the school's system, but VCE still believed I was. My academic transcript had a grade for unit 3, but N/A for unit 4 and the exam. It had no effect on my ATAR at all if that's a concern, it simply was ignored as if I never took the subject in the first place.
