You have an important part to play in the recovery of your loved one but may be nervous or unsure how to respond to them. You may also be experiencing powerful feelings yourself and having difficulty coping with your own reactions.
Support can mean something as simple as offering to take care of day to day practicalities like childminding or shopping. It can also mean supporting someone while they battle with intense feelings like rage, fear, helplessness, guilt, anxiety, depression, etc. Let them know you are there if/when they need you to listen.
