A says: Why are you looking at me like that.
His wife replies:
1) You are going on a long trip again. I worry. That's all.
2) You are going on a long trip again. I am worried. That's all.
Is '1' about a habitual action? She worries about him a lot.
I worry about you regularly and this is one occasion when I am worried about you.
Yes, "I worry" suggests that she always worries when he goes on a long trip so it's a habitual action. If this were the first time he had planned a long trip, she might say "You're going on a long trip. I'm worried."
