Troubled singer Amy Winehouse has been in the news for all the wrong reasons: her jailed hubby, her problems with drugs and alcohol and her eating disorder. Now her mother, Janis Winehouse, has written an open letter to her in the hopes of getting Amy the help she needs. "This letter is my way of making sure that you know that all you have to do is come to us, Amy, and we'll do everything in our power to get you well again," writes Janis in the News of the World newspaper. "We want to help you, be we know that unless you want to be helped — unless you come to us — anything we tried would be in vain." As any caring mother would, Janis reiterated, "Wherever you are, whatever you need, we're here for you day and night. I hope you know that."
