Here is your problem:
Feeling conflicted-disenchanted and damn right mean-spirited, with getting back on my own treadmill, add a dash of culture shock and it has resulted in me lacking focus, enthusiasm and just plain being stuck in lethargy.
You are holding that view in your mind. Don't forget that the universe gives you what you ask for. The genie in the lamp says "You wish is my command" - and weather you realize it or not, thinking "I don't want to feel like X" means you are manifesting X!!!
Instead, meditate on what you do want to feel like. Meditate and concentrate on the life you do want. When a thought about how you think things "are" pops up - parry it with a thought of passionate and positive desire for what you do want.
When you were traveling, you were doing what you wanted. But somewhere along the way, you accepted the thought "I have lack. I don't have resources to do what I want right now" Unfortunately you then manifested that as the truth you are living now.
You create your universe No Face (and I am willing to bet you have a very pleasant face). Do you still wish to travel? Or was there a challenge on your way that made you perhaps start to desire something else? The dark night of the soul is the place we go to remember who we are.
I know of what I speak here, as I have been to this place on many an occasion. And every time I remember that it is I who determines where I walk, then I get up and start walking again to the place I do want to be.
This is the essence of Magick! Make affirmation cards, put up pictures that remind you who you really are and what you really want. Perform rituals that bring this into laser sharp focus in your mind. State as fact, that you have right now, what it is you desire and you will once again be walking the path of Joy.
One last thought: This transformation is the essence of what the alchemists call "The Great Work" the knowledge and ability to turn the base things into precious things, lead into gold. You are the Great Work. Each of us is.
