I can’t stop constantly worrying about my dad and thinking he is lonely, even though my brother and I visit him each 1–2 times a week if not more, and my oldest son lives with him. Still, for the past three years, his ability to speak has become so diminished, he is too shy to be social anymore, my mom passed in 2014 and that is when it got worse. I feel the fact that he has no one to talk to is making it worse. I am currently taking him to a new neurologist to find out if he has Parkinson’s (his tremor is bad) and he put him on medication, but is this enough. Should I stop worrying if he always tells me he is alright, or is he just being nice? I live 5 minutes from him and so does my brother, he asks for help when he needs it, but when I’m not busy, I constantly worry that I should be spending more time with him. Is this my guilt or what?
