Brian,
Hopefully you will be able to travel more. This too brings me great joy, even if it is just walking around the neighborhood.
Hmmm...I've come to the same conclussion. No one person makes me whole. I have found that when I place all that into one person it usually backfired. Such expectations are unrealistic. What I realized that love, acceptance, and forgiveness of self was something I struggled with. This they can not take away when they leave me. Only I give to myself. Hard to explain it.
Not alone with those feelings that there is more to life than what we do. And yes you are ment for great things. We all are.

And the strangest thing might be that little thing we do that is big. Who knows if that stranger you smiled to was having a very bad day and needed some kindness even if they were being grumpy bears who wanted to take your head off. Or that stranger that is paying for their groceries and does not have enough change, sparing a few cents might mean that they eat for that day.
You refer to it as being, I call it simply existing. I too stuggle with the meaning of my life. This I found is something we have to discover out from what our enviroment tried to program in us. Somewhere deep within our core lies the answers we seek outwardly for.
Do you think that attending on-line classes might help? I did this for a semester of studies. Only thing, did not care much for not being able to get ahold of the professors if I had questions before certain lessons were due.
What seems as a negative is sometimes something possitive. We just cannot see it at times because of the barriers we place up. What if you had majored in something you later found out didn't bring you joy but were stuck because you had student loans to pay off?
I don't mind you sharing. This I truly enjoy reading. Glad you were able to open up and hopefuly smile.
As to the still out there somewhere yet to be nourished into existance...perhaps what is existing is in need of nourishment.
Safe Journey
