well... my experience I guess is a little different from the ones posted already...

Yes... I did it.. I called the covering T.... yepper I did...

My T was out for 8 weeks... for medical... and it was emergency for her so not planned..

and I had a very bad meltdown.. so I talked to the covering T over the phone.. a few times during that 8 weeks...

She was somehow able to "center" me and get me back on track... maybe she was just really special.. but it worked... I needed someone, she was there.. and I was really grateful....
