Do I make a difference to anyone?

Since I have had time this year to sit around and think about random stupid things it always crosses my mind about the life that I have led. I wonder if I have made a difference in someone life.  I just wonder if I matter. If I touched someone and left a mark on civilization. Everyone needs reassurance sometime in their life and at this point in my life I do need it. I need reassurance to feel whole.. Yes I do.. Not so much reassurance but something letting me know that I did matter in this life. To more than one person outside my family. I was never really raised to help people other than myself I just took it upon myself to make sure I try to leave this world touching someone hoping that I have left it better or helped someone in a hard time. I just wonder if I am missed. 

In no way am I trying to reach out and get people to just contact me out of the blue from the past or anything. I just think it is amazing that we are all really independent. 

We cannot feel what pain feels like for someone else. 

We cannot know what someone else is really thinking. 

No one will ever know what something feels like to another person.

I do not think we will ever get the truth on some things from someone. 

In this day and age where information is possible to find within nanoseconds and an innovation called Google, as I sit here and try to describe what I am thinking and feeling right now to invoke the same feelings and thoughts in someone else, we are really no closer to bridging the gap then we where 2000 years ago. 

We are still our own islands. We can only guess what something like love feels compared to someone else. We can only guess what the pain feels like to be tired compared to someone else. We have nothing to really tie us to anyone else. 

I know that our past experiences are relative to our future experiences. What we have gone through will ultimately determine what we will put up with or which path we will be choosen when the same choice arrives in front of us again. 

I just wonder if there has been a difference made by me and what people will remember about me.
