From where I sit, don't EVER apologize for getting things out like that. I have no idea who you are, or who your mother was, but I can tell you this, from reading that post, I am inspired.
I deal with my own petty low self opinoin issues, and am taking wellbutrin and paxil to try and cope, but I have not endured a fraction of what your mother did.
To hear about someone that dealt with so much adversity, and must have felt awful failure (I'm sorry, I'm making an assumption) about the condition of her sons...well, I just can't imagine that I'd have the strength to persevere as she did.
Your mom chose to address adverse conditions with strength, and that is admirable. May God protect and comfort her soul, and may your rememberance of her live on as a lesson to others on how to live.
Peace to you, and there aren't enough hugs in my life to give you.
