I'm only human

Yeah I've got patience but don't test me...

I might be smiling but inside I'm stressing...

I might be strong but I'm not invincible...

I might be stubborn but I'm reasonable...

I might seem cold but deep down i worry...

I might be aching but I'm always happy...

Yeah i make loads of mistakes but I'm not a demon...

Don't expect me to be perfect because I'm only human...
