Patty's Chemo and Radiation

I was diagnosed with anal and rectal cancer on May 24 2017. All my doctor appointments have cost me a $55 copay and I have at least 3 appointments every week. I just had a medi-port put in for chemo and up front had to pay $631.00. I haven't even started treatment and I am broke. I will be on short term disability and end up getting about half my weekly paycheck. I own my house so I do not have a mortgage but I still need food and pay for electric and water.
One heals faster when they are in good spitits but this is making me worry so much that I feel like not going through with the treatment. I have to or I will die so I need help with this.
I am a 62 year old who has been widowed for 29 years and taken care of myself all these years.
Thank you so much for hearing my story.
