You must be exhausted, and feeling trapped. I know you want to do the best you can, but give yourself some grace. I'm so sad you're feeling so much stress and pressure. UTI infection? So common. Do you have anyone to give you some respite time to give you time to sleep?

Do you have Physical Therapy staff coming in to help keep him mobile?

We need to help each other, and I feel your frustration. My husband is doing well but I'm with him mostly 24/7 and that's just hard! But it's what we do. I remember he told me when he was first diagnosed, "You didn't sign up for this." To which I responded, "in fact, I did." We've been married 54 years---magical times, wonderful family, but somedays, one more buzzer for help challenges me to take deep breaths and respond with kindness. Not sure I always do that well. We must remember, God is with us. He is grieved at our troubles. He walks with us. Wants us to depend on Him. There are many words in a the Bible to show us how man has always struggled, but He created us, He is always with us. We are never alone. He created us not to suffer, but to glorify His name.

Remember, you were created for a time such as this! God Bless!
