I was texting my mate and I was like
'you always find me somewhere anyway, ya stalker'
And he was like "Pssh, it's all you."
I sort of know what it means but I'm not 100% sure if the meaning I know is correct?
And I don't know how I should reply to that text :/
Help me!
I suggest this:

Pssh, it's all you = Oh, that's only in your imagination

Wht does it mean it is all you
