i was thinking about this very thing the other day.

it seems for me that when i can see and remember that my T is there and will be there for me and we are getting along and OK with each other i am fine with however long the Waite is.i feel connected and i tend not to think about it much(Rare as this may be,it does happen)
but when i am in a lot of pain and confusion full of fear and doubt .worried she hates me want me away from her .i don't want to deal with her.etc..and all these other horrible things that plague me in between sessions most times is when i feel it is forever before i see her again.i want to grab on like a vice and never let her go because i feel i will loose her forever.even in my mind.she will disappear.and it isn't until this next appointment that there is proof that this didn't happen.

i don't know if this is why the wait is like this for you,i may be way off base .but i know it is like this a lot for me
