Help us help our mother

It's been a long unexpected week for my siblings, family & I. We have had another tragic situation involving my mother who is 44 years old. She went into cardiac arrest on 10/7/17. Unfortinutly she lost oxygen to the brain for a substantial amount of time causing a lot of medical issue. She now has an extreme issue with her brain which will leave her with a poor quality of life. We need to prepare for what's to come in the next few days. On 10/13/16 we lost our father so losing another parent isn't going to be easy mentally or financially so I'm asking for all the help possible as we are still recovering from my fathers death. this whole situation isn't easy but my siblings and I are left raising my 8 year old sister who now will grow up with out any parents which has to be the hardest of everything. So please any amount small or large would help towards medical bills & funeral arrangements !! Please share ! Thank you in advance !
