Support can be practical, informational, emotional, or friendly.
Practical support serves to meet concrete and practical needs. For example: Someone who can do the grocery shopping or baby-sit.
Informational support serves to provide information and advice. For example: Someone who can tell you what to do if the baby is sick.
Emotional support serves to provide a sympathetic ear and validation. For example: Someone who will listen to you vent when you are having a bad day.
Friendly support makes it possible to have fun. For example: Someone to take a walk with to clear your mind or think about something else.
