Bewerbung für Alten- und Krankenpflege

Bewerbungstext:

Hello sir/ madam,
I hereby apply for a volunteer year in Germany in taking care of children or the disabled. I can speak some Germany and English and I have been going through nursing training for the past year in an institution in my country. My whole life I have been talking care of children and one of my grandma who had diabetes and hypertension which granted me a great experience in such areas and I think I will do my best.
I am looking forward to positive feedback.
Thank you
