Tell me how alzheimers effects you and your speaking abilities?

I was diagnosed with Frontal Temporal Lobe Dementia and was told that it would turn in to alzheimers because it is now effecting my speech. I'm finding out more and more that my mouth has a mind of its own.!! What I'm thinking is not what comes out of my mouth. Is there anyone else experiencing any of that? Being diagnosed almost 2 years ago, the doctor said that I would need 24 hours of care and I'm terrified about my family putting me in a nursing home, I'm only 57 years old and I feel like I'm losing my mind?? Just because my words are not correct!!!
