What does God want me to learn from this?

Yesterday, I was talking with a friend and I was saying how I wished I had a job and also how I was super worried about college because I haven't heard back from any of my colleges (and one college I applied to a couple of my friends also applied to and they have already heard back) and how no one wants me to be productive. I didn't tell my friend, but I was crying because the idea of the future–which is unknown–is frightening to me, and I'm so scared I'll never get a job or get into college (also because I'm just a crybaby haha), and also I'm still depressed that I didn't get into the talent show again. Well, my friend said, 'Listen Mattie, think of it like this, don't ask "why do I not have a job right now?" ask "what does God want me to learn from this?"' He also said that "pearls given are rocks, pearls earned are priceless", meaning that finding things out for ourselves is a much sweeter reward than just being given the answers.
He also gave me this poem:

"My life is but a weaving
Between my Lord and me,
I cannot choose the colors
He worketh steadily.
Oftimes He weaveth sorrow,
And I in foolish pride
Forget He sees the upper
And I, the underside.
Not till the loom in silent
And the shuttles cease to fly
Shall God unroll the canvas
And explain the reason why.
The dark threads are as needful
In the Weaver's skillful hand
As the threads of gold and silver
In the pattern He has planned."
(Unknown)

And I thought, "Sure, these are great words, but I'm still so scared and I don't know what to do." And I follow this blog that I go on reading splurges–when I first found it, I read the blog posts for hours and then I didn't really read any more until yesterday when I went on another splurge–and I was reading it yesterday and she said some things that hit home. God will always send us what we need. He sends us who we need, and He sends them when we need it. Never before we're ready. He only sends us answers when we are ready for them. And I love that. Sometimes, the answers are not what we want or expect, and so if we receive them before we are ready, we won't understand. We need to be humbled before God can give us the answers that we need and will be able to understand. We may not always understand why He gave us the answers He did, but we will be humbler and more ready for the answers. We need to humble ourselves and look for the answer; only then will God reveal His answer and plan to us (in pieces). He doesn't just give us the answers; I saw this thing that said, "The teacher is quiet during the test", and it's true. God doesn't just hand out answers willy-nilly. We need to work hard for them. I know that He loves us, and I know that He will help us if we ask Him to. So, to answer my question, "What does God want me to learn from this?" Right now, I don't know what He wants me to learn. But I am definitely going to find out soon.
