For the last 10 years I have dealth with and overcome depression which stemed from my relationship with my dad who mentally abused me over the years. Recently my older sister told me that he hit both her and my other sister and I witnessed it constantly from when I was aged 5 to 10 years old. I cannot remember any of this and can recall few childhood memories when I was that age. I think I have blocked all of it from my memory. How do I unblock the memories so that I can heal and continue with my life and leave my dad and his anger behind?
