When living in Spain I worked for 18 months as a live in carer for an older lady who had had an accident, she had a broken shoulder and ankle. she was also having difficulty breathing due to lesions on her lung. She was during this time very vulnerable and relied on me entirely.
My duties involved organising her many medications and giving daily injections.
I also did the housework and took care of her 3 dogs.
Other duties included taking her to and from hospital and on days she was well enough I would take her to visit her friends.
I believe I have the necessary qualifications and skills to successfully fulfil your requirements.
