My Grandmother and i need your help

Hello Everyone.

My name is Tasos and I live in Greece.
I am making this funding project because of a person that i love the most in this world. My Grandmother. She is 76 years old and she is living with her son (my uncle) who is 58 years old, in a house which is in a really bad shape.
They both have health problems. My uncle cannot work because of a serious injury in his back. They are living with a small amount of 350 euros per month, which is my grandmother's pension.
As you can see from the photos, they live in very bad conditions. They only way to warm up is an oil stove. My Grandmother lives with support of oxygen because sometimes she cannot breathe. As you can see the house has a lot of moisture on the walls. Also it is a house that is not build yet and it is incomplete. The floor is bad and it is covered with carpets. They were forced to live there because they could not afford renting a house. So it was their only way.

I was trying all of these years to help them by collecting food, clothes and everything i can afford. Umfortunatelly i am renting a house and i cannot do more about them. And i am really sad for this. Some days ago i had a talk with my Grandmother. She is a wonderfull person. It was the first time in my whole life that i saw her crying. She was abused by her parents when she was young, abused by her husband later and when she lost everyone, she tried to raise her two children. My uncle who is still with her and take care of her and my mother. She remembered all of these difficulties that she had in her life. I tried not to cry infront of her when i was listening to her. She told me that she is going to die and will never see the house she was trying to built completed. I went to the toilet and i cried there. She has so many pain inside her. She deserves a better life. She deserves a better place to live in. And i was thinking how i can try to help her.

So i reached out this website. I don't believe in miracles. BUT I believe in humanity. I believe that together we can make each other smile. This is the reason i am calling for your help. I want to see her smile again. Like when i was a kid and i was living with her. She raised me up as well. She lived a life full of difficulties and she is still a fighter.
I would really appreciate your help so we could all built the house and live the rest of her life under better conditions.
