As requested by Matt79. As it turns out this is harder to describe than I thought it would be, I think the easiest simple explanation is that safe people are to me what a favourite blanket or particular stuffed toy is to a child-security. I can go pretty much anywhere and do what I need to if I have a safe person with me, I don't need them glued by my side just the knowledge they're there and I can find them if I need to is enough. Examples of things I can do comfortably with safe people but freak me out on my own:
Going to a movie
Going to any sports/social event (although even with a safe person crowds freak me out a bit)
Going out to eat
Catching public transport
Actually the list is pretty hugely long, the only things I don't do with a safe person are at home (another safe place)-I quiet often spend most of my time alone at home. It's a bit like giving yourself a needle, nearly everyone is capable of doing it, nobody wants to do it and if you don't have to you avoid it as best you can, that's what doing stuff without my safe person is like. Of course if I can catch the train with a safe person it stands to reason I can do it by myself, but its an anxiety inducing thought so I avoid doing so. Worst still is the fact that even if I force myself to do it a few times it doesn't seem to make it all that much better, I'm apparently hard to desensitise. And then theres the fact that in social situations if I was as confident as I am with a safe person it'd go just as well as when I had my safe person, unfortunately I'm not so I get all nervous and say stupid things and sweat. A safe person is basically someone I trust implicitly to back me up, for example my friend K is like half a safe person, I don't trust her to back me up implicitly and sometimes she'll make a bit of fun or not want to leave when I'm uncomfortable, therefore most of our outings (few and far between) have an undercurrent of anxiety and tension from me. So it's very hard for me to imagine doing everyday things that a lot of people take for granted, I've found a lot of info on social anxiety on the net but not such a lot of info on 'safe' people-I'm assuming it's either not all that common or most people with anxiety don't have the luxury of having safe people. I think safe people might actually be a section of agoraphobia-instead of a safe place you have a safe person. I'm not entirely sure.
Hopefully that makes things a bit clearer,
