I put between 1 and 5 because of the "close friends" description, but in actuality I have a much larger support system than that when I factor in family, church, coworkers, etc. I've discovered not every support person has to be a "close friend" that I confide everything to. Some of my best supports are the people at work who help me out if I need to leave early for an appointment or the church choir members who bring meals to my family when I'm in the hospital giving me some peace of mind. When I factor in the number of people I know I can count on for support in some way, that number goes up to closer to 20, so I feel pretty blessed that way.
