Song written by 16 year old, what do you think?

Idk if I like it yet, I'll probably change some things before it's finished, but let me know what you think about what I have so far, if there's anything you really like or if there's anything that you want me to change :)

If you have any tips or ideas, let me know :)

I don’t understand…
The way I still long, for the touch of your hand.
I’ve been hurt too many times before,
Said I was through,
But you keep coming back,
Knocking on my door…
And I let you in.
Well, I’m not gonna let you win again.

What happened to my confidence,
Why are you acting innocent,
When you’re the one that did this to me…
You’ve tried to play these games before,
But I can’t take it anymore…
What happened to my pride?
I’m starting to believe your lies…
And oh,
When did I become,
The insecure one?

You seemed so perfect,
That I was ashamed…
But who said that means you can beat me down?
I only have ONE name.
Beauty’s only skin deep, you didn’t pass the test.
It’s time for me to move on,
You never cared about the rest.

What happened to my confidence,
Why are you acting innocent,
When you’re the one that did this to me…
You’ve tried to play these games before,
But I can’t take it anymore…
What happened to my pride?
I’m starting to believe your lies…
And oh,
When did I become,
The insecure one?

I need time to find myself again,
You need to go,
I don’t wanna stay friends.
You tried to keep me under your spell,
All I have to say,
Is you can go to hell!

What happened to my confidence,
Why are you acting innocent,
When you’re the one that did this to me…
You’ve tried to play these games before,
But I can’t take it anymore…
What happened to my pride?
I’m starting to believe your lies…
And oh,
When did I become,
The insecure one?
