Hello and welcome from me and I'm sure all of us on the site here.
May I ask is Ethiopia where you or the person you care for now live as it will alter the advise about benefits and things.
Meantime just welcome. K
I hope you are getting some help and support for your father. It`s very hard and exhausting when no help is available.
I also hope it will help you to share your experiences with others here. There is a lot of understanding because we all know how it is and other members are generous with their support.
