It took me about two years.
I do feel stronger, although my self-esteem is still pretty bad, and that occasionally still leads to suicidal thoughts.
But other than that, time and effort heals most things.
And just something to note, don't hate your mother, hate, (if you have to), her actions, becuase your mother was sick. It wasn't her fault. This transition may seem unimportant, but I think its connotations into the structure of the family dynamic and the subconscious are very, very important.

Never lose hope.
