What do these lyrics mean?

Electronic music, sang by female:

I don’t wanna laugh
I sometimes want to cry with you
You could see my smile
if i stop thinking too hard

when i am this upset
I cant get out
I cant do
cant impress you

Chemicals in my hair
are the ones in my head

Love may take me up again

I was chasin’ you
were walking
where id like to see myself
if you wanna get with me
protect me from me

i’m a victim you’re a dream
im a dreamer every now and then
if you wanna get with me
you need to help me save me
