Looking for the meaning

I feel so upset
I feel so much fear
I´m sorry about these words
I wanna disappear

I´m feeling so stressed
This tought is burning my brain
I gotta take these drugs
To disguise this pain

Insanity haunts me
Like a bad dream
Smashing my heart
I wanna scream

I´m feeling so stressed
This tought is burning my brain
I gotta take these drugs
To disguise this pain
I feel sorrow, there´s no tomorrow
I´m trying to understand my existence
Sometimes this feeling
Makes a mess in my mind
But I have to face
The truth inside
