Widow in Distress

I am a 77 year old woman, a grandmother and  look after my daughters three children. My daughter is a recovering drug addict. For the last 17 years my life has changed drastically. My daughter was made homeless and her children are in my care. One of my granddaughters is severely depressed. I can not afford to care for everyone physically or financially. I am diabetic with heart problems and I have limited mobility. I live off my state pension and have to feed four people with that money as well as pay all my bills. I havebe applied for help but it seems I'm not eligable for pension credit or any other benefits. My boiler is broken and I am without heating until it is fixed or renewed . All I ask is for a bit of support and I would  so very grateful for any donations.  Thank you for listening to my story.
