It sounds like you are very concerned about your stepfather’s safety. First, if at any time you believe that your stepfather is in immediate danger, contact emergency services and do your best not to leave him unattended. Consider talking with him about talking to a professional. Let him know that you and your family are there to support him. Reassure him that it is okay for him to be hurting but that you can work together to make sure that this isn’t forever. Offer to contact a hotline together or make an appointment for help. Additionally, make sure to take care of yourself as well. Talk to a professional for help if you need it and surround yourself with supportive friends and family.
