Once again, not sure if this is the right section for this post. If not, feel free to move it.
I don't post very often, but I feel like in a few places I've mentioned my family situation. I have a father who has multiple sclerosis (ms), he is now at a point where he can no longer walk at all. I have a brother who was diagnosed as high functioning autistic at the age of 5, I was 8 at the time he was diagnosed. My mother is the primary caregiver and breadwinner, so in this period of time where I'm finishing my graduate degree and working full time, I've moved home to try and help them out as much as possible. Admittedly, an added bonus has been no rent, but that's beside the point.
I have no qualms about giving them my time, they're very understanding that I have my own life and goals. I think there was a time where I felt a certain amount of jealousy or just the overall feeling that the universe had screwed us, and I don't blame myself for having felt that way in the past. Luckily, I am able to find a sense of pride in helping them now.
But in recent days, I have realized something. Following a failed relationship and a question as to why I'm so ready to relinquish authority to others, I have come to realize for a very long time, I have subtly believed that I too am developmentally delayed or will one day be disabled. For the sake of the conversation, I was tested multiple times after my brother was diagnosed with autism and it was determined that I was not. As far as MS goes, I've been told it's not genetic, though I don't claim to really be much of an expert in the subject.
But when I think back on my life, I've started to see where part of me believed this. When I was younger and I would struggle with a class or a job, while I didn't make excuses to get out of having to do the work, a part of me simply believed the reason why I had trouble was because I had an undiagnosed delay. On the other end of things, there have been times where I feel I have to do as much as I can before I turn 45 (the age my father was when he was diagnosed) because I will also lose the ability to walk.
I want to make one thing absolutely clear. I logically know this is not how disability works. I'm not looking for someone to convince me that I'm not developmentally delayed or that I will develop a disability at some point, I think I'm simply looking to see if anyone out there has ever dealt with this sort of feeling. I've tried multiple google searches on this but I don't think I'm choosing the right keywords.
Has anyone else here who has provided caregiving or assistance to a sibling or parent ever dealt with this sort of thing? A subtle but present thought in the back of your head that you share or one day will share the disability?
Thank you for your time.
