I feel for you having been trapped once chemically on the other side, where side effects stole my personality and cost me my family, and now a brain lesion has robbed me of my small amount of freedom in the ability to drive and has taken away my only hobby.
BUT… our outward inabilities to express ourselves as the loving people we once were does not diminish the love we feel in our hearts. We have had a huge part of 'I' taken away and can feel trapped, lost and alone. Do not take this as a sign that Love has died.
Draw on the strength of those around you. Come here for support. Know that your husband really hasn't changed inside.
Dave.
