Self-guilt is the act of feeling all the guilt on one's ownself. It can also be intentionally, putting yourself down on purpose. Self-guilt can also lead to depression, and sometimes even suicide.
The guilt projected onto a person that doesn't want to or believe in taking the flu shot vaccine.
You say "No" meaning "I don't want you to inject me with formaldehyde & mercury" and the nurse gives you the flu shot guilt by sending you a look like you just said "there's no such thing as God."
Self-guilt is when you put the guilt on yourself. This also includes low mood, depressive thoughts and antisocial personality. Self-guilt is all in your mind and eats you up mentally and physically.
