Hey Puppetz! You are brave!
You can type up or write stuff and give it to the counsellor to read? Maybe you could even arrange for some e-mail counselling? (Some have this option.) Might also wanna write down any questions for him/her?
It really depends on the person, some people on this board have been quite happy with their counsellor.. There are various options and it's good to know what the person you're seeing uses and specializes in. Is it CBT or other things? Some specialize in SA and could probably be most useful? You can learn a lot from books too (which is what I did).
For introduction to CBT, The Feeling Good Handbook by Dr David Burns is really good!
You can check if your therapist has a profile online, see the pic, read the bio, so you can get to know them a bit? For me, it's helpful to research unknown people for a bit before meeting up..
If you don't click with your councellor you can always go see someone else and see if you two click better? Some see a few to find someone who really helps them. Hope yours will be helpful already! Keeping fingers crossed for ya!!
