@bbcnews: Karen was still using heroin when she got pregnant with her daughter, Abby. Now she is a recovery worker and says the drugs being used now are more dangerous. If you are suffering distress or despair and need support, you could speak to a health professional, or an organisation that offers support. Details of help available in many countries can be found at Befrienders Worldwide. A list of UK organisations that can help is available via the BBC Action Line. #Chicago #US #BBCNews
