This is a matter you want to bring up to your probation officer and your sentencing Judge. Community service is a common condition of a defendants probation, and you are typically ordered to complete it in its entirety. Where hardships arise, you need to bring this to the attention of your P.O. and Judge so that an alternative/substitute condition can take the place of the community service, or the Judge may waive the condition altogether upon a validation of your hardship. Until you get the courts approval to modify your community service order, my advice is to try your best to comply to avoid violating your probation.
