Awww I'm really sorry
I could tell how much you were looking forward to all this.
Hopefully you'll get some other oppurtunity in the future.
When I was younger I wanted to volunteer with animals and foster soooo bad but my mum said no and refused to drive me anywhere.
Now I'm much older I have set up my own little rescue, I'm about to start fostering for the RSPCA and will be volunteering once a week at a rabbit rescue.
So although you might feel a little down now just remember that in the future things will change and you'll have more animal rescue volunteering you'll be able to do
