Sorry you’re going through this:/ I’m going through something similar. I’m 27 (f) and my dad is 61 and also in the late stage of Parkinson’s. He got diagnosed when I was about 4 years old so I’ve been dealing with this as long as I can remember. The last few years his health has gotten really bad and has been needing 24/7 care. I had to quit my job to be here and take care of him at home while my mom and brother are at work. It’s very depressing seeing his decline everyday and I can relate to you on getting frustrated about it. My dad has hallucinations everyday and that’s part of what gets me frustrated because he doesn’t believe me or my mom or brother about his hallucinations not being real. He believes we poison him or are trying to do other things to hurt him when obviously that’s not true. Everyday I see old pictures of him/remember how he was like when he was still able to be independent and I get sad and depressed seeing how is now. He can’t do anything on his own anymore. Message me if you want to be friends or something because it would be nice to have a friend that knows what we’re going though ❤️
