The statements you are making I can relate to deeply. I love my husband so much, but when you said “I feel like I’m talking to a brick wall” I whispered, “That’s us too!”. Feeling inadequate as a caregiver has been a challenge of mine too. You sound like you’re doing everything possible to care for your husband. Those treatments can really change someone’s appetite and ability to stay connected to daily activities. Correct? I’m sending you a caregiver hug —— you’re doing great!
