Help my dad fight brain cancer

My father, Paul Wyne, has brain cancer and is about to be homeless. Unfortunately, my dad has been recently diagnosed with stage 3 brain cancer.  Now the tumor has been removed on July 22nd 2018.  The Neurologists best guess is that it has been growing over a span of 2 years so it was quite large. Due to the nature of the tumor and my dad not going to a doctor he lost all of his business the last 2 years, which left him financially bankrupt. He has recently applied for all the government help he can, but wouldn't know if he gets accepted or denied till November.  Now everything is covered for the time begin except his rent which is $900 a month and is due in a week. If I am not able to raise the funds for even one month, my dad will end up in a homeless shelter. In turn he will refuse radiation treatment for another 2 months due to the uncertainty of a shelter. My fear is by the time disability from social security (if he even gets accepted) will come, it will be too late and far along to be successfully treated. I have been struggling to find any organizations to help with rental assistance and I myself work out of the country and gave my last bit of savings for last months rent. In hope that maybe the government would step in this month, but that hasn't happened. This is my last reach for help. 

Please if anyone can help by sharing or donating I would really appreciate it. Thank you for taking the time to read through the description and potentially sharing and/or donating.
