@Brokenwings Hello and welcome to this forum! I am sorry to hear that is happening to your younger sister. Sometimes it is really painful to see a love one or a family member is struggling from something and you still do not know what to do in order to help them. Just always be on her side and try to support her to fight his addiction. She is still young and she needs your care and love during this struggling time in her life. Just keep on praying that everything will gonna be okay for your younger sister and for your whole family.
