Husband has frontal brain damage from surgery, upset with challenges

My heart goes out to you. You seem to be doing all you can to cope and exist the best you can. I'm a musician myself. Mandolin is also fun. But the suggestions I see for ukulele are great! It's light weight and easily joyful! And how about a conga drum? Or a small keyboard? It all helps to put smiles on our faces and brings some needed joy into our lives. I wish you the best.
