Angela I won't repeat the good advice above other than to endorse it. Of course its new and scary and it won't be easy. I couldn't have worked during mine but I know others have, especially in the early weeks. Its a journey,a learning curve. No one can tell you exactly how your body will react. The medics can only give you a range of likely side effects, which ones you get and how bad they get depends on your own body, your attitude and measures you take to minimise the symptoms (pain relief, nutrition etc).

You'll be sick to death by now of the cliche "stay positive", but it is so important. Keeping yourself calm, optimistic and relaxed about things beyond your control helps the healing process enormously. Optimism and pessimism are both extremely contagious. Keep your chin up and you'll do fine.
