I can so relate to what you are sharing about your loneliness. My husband too has moderate dementia. I cannot leave him alone in the house. It would be like leaving a toddler alone. This keeps me from going out and doing the things that I enjoy so much. I have a baby monitor so I can be out in the garden and still know when he has gotten out of bed. It is so painful to see him as he is now when he was so smart and capable and funny before the dementia journey began. Family and friends can't know the extent of the changes you see because they don't live with him. I have found comfort and support in this space where I can share my situation with others who understand. The posts here remind me that I am not alone. I have researched and educated myself on the positive approach to caring for someone with dementia. It reminds me to look for the things that my husband can still do and let go of the things that he will never do again. I also bought a daily reader of devotional readings for caregivers that I start my day with. It helps me remember that there is a higher power that will always be with me on this dementia journey. Reach out to others that are on the same journey. It helps to share what you are feeling with those that can understand. You are not alone. May God bless you and your husband.
