Give yourself time and maybe you will be lucky enough to forget.
Time and human distress travel in parallel paths. Time does not heal. Human beings just get better at tolerating it. You get conditioned to the pain, making it a habitual part of your existence that puts an unstable mind into a more stable state.
Human beings do not like an unstable state of mind. Time is relative to pain in the sense of making us more tolerable and later immune to what had hurt us before.
