Mirrors

Ever since i was a little boy mirrors have given mw cause for concern. I cannot look in a mirror from any angle in the dark and in the light i still run when my back is turned to them. I do not know what im afraid of but just sitting here typing this is giving me a panic attack. Do you know those dreams you get that scare you and you try to scream but nothing comes out? I get that in real life. My family has found me cowering in the shower unable to talk and later when ive calmed down i was unable to tell them why the mirror scares me. As a child my parents shielded me from the scary movies and stories revolving around mirror s and in adulthood i still dont watch them. This fear is seated deeo within my very being and it has caused problems in relationships. Any advice to help me get past this?
