Logic

“You have to love yourself before you can expect anyone to love you”.
How can you expect me to believe I am worth loving if no one loves me.

If P, then Q
Not Q
Therefore, not P

Thus

All P are m
No S are m
Therefore, no S are P

And I am not worth loving.

I win.

[although: while I present a valid argument, it’s based on deductive reasoning, in which a false conclusion could be reached – if a premise were to be false…and I appeal to your ignorance because what you don’t know is that your argument would take the same form, thus also being valid; while neither is necessarily TRUE damnit]
