taking a guess here that its normal for people whether they have DID or not to have anxiety and triggers when their t goes on a long vacation...

reason I say that is because I have non DID friends who have their own treatment providers and they sometimes have a problem with when their therapists go on vacation, especially those friends that have bonded very closely with their therapists or have had the same therapist for a while.

another reason I say this is because sometimes I read the psychotherapy boards and there are lots of members who have all kinds of mental disorders or are in therapy because they needed help on issues related to their spouses, children or others with mental disorders, who have posted that they have or are having a problem with their therapists going on vacation.

directly related to me... all my alters are integrated and still sometimes I have a problem when any of my treatment providers go on vacation. many of them have given me something that I could hold or do, that when I am missing them or having any problems related to them not being readily available including vacations that help.

maybe you and your therapist can talk about this and come up with either an object or activity/ homework for you to do while they are on vacation that can help with your anxiety.
