Help for David Higginbotham

My dad David Higginbotham was diagnosed with stage 4 Colon Cancer. He was told by his boss when this all started he would be fine and have his job to come back to. Well he is not doing so well. The surgery he was supposed to have to remove the tumor could not happen because it had gotten larger and spread.  So he is now on very powerful chemo to help shrink the tumor enough to remove it. He cannot work due to this condition. He has had so many side effects from the chemo. He cannot eat and is in lots of pain. So he has now been let go from his job.  His insurance has now went to cobra and he no longer has life insurance.  Disability will start for him but not until January.  The family has raised money so far to help with his mortgage and medical bills but now without any income coming in until January we are all worried about how he will be able to live. This is our last resort to help him be able to keep his head up enough to try and fight this cancer.  We never wanted to have to do this, but it seems every time we think things are going ok we get more bad news. Anything you can do to help him will be greatly appreciated:).
