Happy belated father's day to your father! I stopped talking to mine 4 years ago, he was not a good father, but I think all fathers have at least a bit of love for their children, it's nice that yours is still with you!
I hope he can find a treatment that helps reduce the symptoms of Parkinson, best wishes for him and your family!
I'm so sorry to hear that @ralk98. Cutting ties with a parent is always really hard - even if they weren't a good parent. Thanks for leaving some encouragement for my dad and our family. <3
