When you have not been allowed to feel real sorrow, or have not allowed yourself to feel real sorrow, the resulting sham of an emotion is shame.

Shame and guilt are not normal human emotions. Shame has no source within you--it is something that has been dumped on you. Do not confuse shame with the powerful energy of remorse.

The only first aid of which I am aware is to realize that shame is something that has been caused by another, or others. It can be ended.

See a practitioner for a course in ending shame.
