I've been in this situation in my first year at university - I transferred to another uni to begin a similar course and found myself so much happier. Unis that have spaces will have a little bit of wiggle room for the first couple of weeks as students move around courses internally so it could be worth investigating there.
You can wait it out to see the outcome of the appeal, or you can see what your options are according to your course rules. I could have been allowed to continue with the need to make up for the missing module in my second year. I would have also been allowed to complete a resit not in attendance - essentially just sitting my examinations and taking a gap year. You won't be the first person to be in this situation, and from a university point of view, they want you paying them tuition fees much more than they want an empty seat.
Most importantly; do not freak out. Don't make any fast decisions and don't think that this is catastrophic. Many of us have been in similar situations for various reasons and there's always a route through anything that happens. It took my 6 years to complete my degree but it was definitely worth it.
