Ok, try not to worry, you will figure this out.
First and formost, try to find out what is in the rabbit pellets, (and brand name) some rabbit pellets are absolutley no good, others can be worked with if you truely cannot find Guinea Pig pellets. There are two problems with rabbit pellets, the worst is they do not contain vitamin C, but you could supplament this with human vitamin C tablets (try to get a low sugar type) and or providing veggies and fruit that have a lot of vitamin C, like red peppers, oranges, cantalope. (There are others too).
It is also very important that the rabbit food does not contain any sort of medications ([FONT=Arial]antibiotics[/FONT] in particular) that are often added to rabbit food to help them fight off common diseases, (especially in feeds that are used for raising commercial rabbits sold as food). If the food does not have any antibiotics, then you may be able to use it, just make sure you enrich the diet with vitamin C. (Do not use drops for the water).
Another option is to go with the HAFF diet, which is mixing up the right blend of veggies and fruits everyday so that you don't need pellets.
Do you have access to unlimited grass hay? That is really important. What fruits and veggies are you feeding right now?
Please read over the Common Misconceptions thread in Cavy Chat, it has a lot of great advice. Also,
