I give up!

I work hard taking care of our ederly every day. I am studying to be a CNA and I only have 2 days of clinicals left. I love working in the nursing home and do everything I can to give my residents the best possible care that I can. The problem isn't at work/school though it's at home. It seems like every day I have to listen to someone complain that I am not doing enough around the house. When I come home in the evening I have been on my feet going from room to room all day so I am tired and my feet hurt. I am so tired of it all I am ready to just give up.
