OMGosh! Sounds just like me. Married 53 years to a needy husband who now has MCI and is low key somedays and all over the place other days. I'm trying to find a therapist for myself to deal with the emotional stress but meanwhile, my daily devotionals and Abide meditations are really helping. Having huge meltdowns are not good for my own health. I've made the commitment AGAIN to try to be kind and not say hurtful words which I end up feeling guilty about later. It's hard because I'm half Italian and have a temper. It's not worth the stress at my age to yell at someone who can't understand how or why he upset me anyways. I'm back to prayer which is the only place I am able to find comfort and peace. This helps me stand back and be a little more objective. AI answers on the internet are helpful too when asking about dealing with a husband with MCI. I'm here if you need someone to share your feelings with. I get it and it ain't fun.
