It's ok to be nervous before your appointment with Linda. It's actually a good sign. It means that you are confronting your feelings and getting to the issues that bother you the most. I'd be worried if you went in there feeling like it's no big deal. That would tell me that you are not working on your issues at all. It doesn't necessarily have to be painful to be beneficial to you. You can gain insight or talk through something that before bothered you. And Linda is there to help you and she does care about you. Keeping those things in mind can help.
You really think this stuff through well! Being a therapist is risky, but it is also beneficial in that you can usually see when a person you are working with is starting to have issues pretty easily. The risk is still there, but most clients are pretty obvious (and therapists see a little deeper) so it's not a surprise when the person is having trouble in their relationship with the therapist. And all therapists (I hope!) have been trained on how to deal with transference so working it out in therapy is a must.
Let me know how it goes tonight. Also, just to let you know, I will be away from my computer during regular times from this Sunday May 13th to Wednesday May 16th. I will try to check in, but I'm not sure I'll have access to internet (out of town trip). I didn't want you to write and not be able to get a quick answer. The place I am going hopefully has access. I plan on checking in during the morning and at night on JA if I can get the computer to work!
