Where do I start?

I am feeling a little off these days.
I do not know what I need to change in order to feel better.
???
I know that something has got to change.....but what?
I think that I need to get more into the world.
If that makes any sense.
I do different activities, but always alone.
almost, always.
I think I need more intimacy.
Not in the sexual/romantic sense.
Just in the human sense.
I need more interaction with new people and new activities.
maybe I need to be challenged.
Expand my comfort zone.
Push my limits.
Get creative in some new way.
Resource my vital energy.
