Strength and understanding

Please pray for strength for me each day, understanding and kind words. My husband is in his 80’s and needing care. He doesn’t remember very good and puts himself in danger of falling each day. He doesn’t listen and remember what I tell him so I get very frustrated and yell at him quite often. I go to bed at night and feel like I have degraded him and abused him verbally almost every night. I really don’t like what I do to him and just go through the same thing everyday. I feel so awful and sad!
