@worrywife Welcome to Mayo Clinic Connect. I'm glad you stopped by here and have already had some good ideas sent to you! Here is the link to the group that @vickie1320 is speaking about: https://connect.mayoclinic.org/group/head-neck-cancer/

Ask at the cancer center where your husband was treated, to speak to the social worker. They are there for you, too, not just him! They will be able to offer resources for you both.

Recovery can take a long time. Life is simply not the same, anymore. As a patient undergoing current treatment, for me it has been over 3 years on chemo for a blood cancer. Only recently have I felt more like returning to my hobbies and interests. Each patient is different. Setting small goals is important. You say he cannot sleep? Does he find rest when in a recliner? I do, and my husband is very understanding to know "whatever it takes". Likewise my energy some days is just not there. I make a list of what I will do in a week if there is energy. Pick the must-do items, the rest are a bonus. And nothing says any chore has to be completed in one sitting. Getting out and moving can be real beneficial; walk around the block, slowly, and aim to speed up a bit every few days. It's a slow return, and takes a lot of understanding from you both, and support.
