Father of 5 seeking help for medical bills

My name is Miriam Garcia 16 year old and my father is Misael Garcia. I'm trying to start this fundraiser to help my dad with medical bills. I'll tell you a little about him he was married to my mother, they were together until I was the age of two and they separated she came back into our lives when I was six years old. He gave her an opportunity because of me my dad had custody of me they had two more children my mother then again walked out on us again this time it was myself and my two sisters.  My dad raised us alone for three years and got with another lady that relationship lasted one year she was very abusive verbally and physically to my sister's and father.  My dad got with my step mom now and they have a 9 month old and she is currently pregnant... So on August 10th my dad was working outside he is a welder and was grinding some metal the disk from them grinder exploded and he lost control of the grinder  the disk axed his fingers semi off. The doctor has given him a 5% of movement to his hand and I have faith in God that my dad will have a greater percentage of mobility to his hand. He started therapy, it is a minimum of three days a week and out of pocket is 150 dollars after a forty-five minute session a day. That is a total of 450 dollars weekly that we currently cannot afford. I'm asking for help so he doesn't stress out over medical bills and therapy so if I can please get help to help him. He is my heart and soul and has done so much for us. He has been the only person to ever give my sisters and I stability and I would like the opportunity to give him that as well . I want the chance to be his rock.
