I want to be a strong tree...

Jeremiah 17:5 thru 8
"Thus says the LORD, "Cursed is the man who trusts in mankind And makes flesh his strength, And whose heart turns away from the LORD.
For he will be like a bush in the desert And will not see when prosperity comes, But will live in stony wastes in the wilderness, A land of salt without inhabitant.
Blessed is the man who trusts in the LORD And whose trust is the LORD.
For he will be like a tree planted by the water, That extends its roots by a stream And will not fear when the heat comes; But its leaves will be green, And it will not be anxious in a year of drought Nor cease to yield fruit. "

I am still pondering though...what does "whose trust is the Lord" mean?
I have recently realized how anxious of a person I am...I am constantly thinking not just daydreaming...scheming. This use to be a kind of witty and funny trait but over years of letting this trait go unchecked, it has become a type of vine that is slowly sucking the life out of my tree. Anxiety for me is worrying constantly in hopes that if I am always thinking it about a certain thing then surely I will eventually think a new response and it be the perfect solution to avoid trouble, have the most, or prevent something all together. Thinking about something to the point of ignoring other life giving and exciting topics ( that would be worth entertaining ) does not change a situation. An example - Thinking about our budget for the next week incessantly, doing the spreadsheet literally ten times a day will not change the amount of money I make - it's the same and completely unchangeable by me. The amount we owe on bills will not change if I retype them in over and over...BUT somehow I have told myself that by spending that much time OBSESSING I am being a more faithful steward of what we have...BULL...what we have is what we have and God would find me more faithful if I would follow the command "Do not be anxious..." rather than following the self created command "Worry, work it out and wait for it not to change". Satan traps us so well...he does not want me to feel like life is under control...God's control that is. he does not want me to realize that there is joy in not knowing everything. he does not want me to recognize God providing or God being true to His word and as long as I try to hold it all in the palm of my hands I cannot step back and realize that HE has it all under control and even happening exactly the way that HE knows it needs to.

So I want to be a tree...a person who trusts in the Lord, who stands strong and is unshaken by the storms, the trials, the things of life, but rather stands with confidence, with fruit (joy, peace, love, patience, etc.). Rooted enough that I will stand still rather than trying to run in circles all the time trying to fix everything or get everything all at once.
I want to throw my worry to the stream ... I want my anxiety to quit choking out the fruit in my life. Lord help me...
