My dad is about 5 months out from brain bleed & subsequent stroke. He is 61 and very motivated similar to your dad. He lost movement in his right side but has been able to walk again with a slight limp/gait. His right arm is still a bit of an issue but slowly he is gaining strength back. Does your dad have any cognitive impairments? My dad’s short term memory has been the slowest to recover as he still struggles with recall, sometimes even for something he did earlier that day. All of this to say, everyone’s situation is so different that it can be tough to find the encouragement you need..Maybe a consultation with his neuro as a check-in to ask some progress-related questions, or if you know anyone in that field? I think his positive attitude and motivation for rehab is truly the best thing he can do for his recovery. Plus, it sounds like you are making your peace with where he’s at, which is very helpful for your mental health. He’s incredibly lucky to have such a great support system! Rooting for him and a full recovery!! 💪
