Worst mom

Ever feel like you have been a total failure to you kids. With the events of the last few months that's where I am at. I take one step forward and 10 steps back. I have failed at teaching my children many many life lessons and am not sure how to teach them now. I have spent the last few months in heartache and the last few weeks the heartache has been impounded by decisions and actions of my children. I wish I had the answers. I wish I could turn the hands of time back to change what and how I taught my children. Lately I think I was not meant to be a mom. I have messed up the responsibility of my greatest blessings.
