Hi AliceKate,
I am glad it helped.
There are different types of talk therapy,more than I can list here. I am not a therapist so not entirely sure I am using right terms next...someone feel free jump in.
All talk therapy I have had you sit with a therapist in a safe, quiet room., Mostly I sit up in a comfy chair unlike cartoons normally people are not laying down. Other people in same building and nearby in other rooms which makes me feel safer.

You bring up things that have happened in the week or bother you., Or stuff from past been on your mind Therapist will ask questions or make comments that help you understand what happened, give you insight why you responded or acted a certain way. Sometimes therapist will.mention something you said before.from your past, help connect it to a way you reacted recently. ifI am really uncomfortable or get scared, I say I don't want to talk about this anymore. Therapist will typically change subject right away, or ask what you want to discuss next. Rarely have I had a therapist try to continue pushing me in that direction in that session. Now later on, that subject may come up again in a slightly different way. If you are uncomfortable.or scared you say that, and therapist may help you figure out why you are scared right then.

Some talk therapy deal with really deep stuff you may not really conciously know, and this type is psychoanalysis (not sure right name) like Freud but up to date.. Like slow building talk. Good therapist works with you slowly in this type,and it takes more time, very regular sessions, benefit is over time.

Cognitive behavioral therapy is different,helps with more specific goals, takes fewer sessions compared to the other type,and teaches changing how someone sees a problem and they change their behavior, and then over time your gut reaction and feelings change to match. Like pouring milk from a bowl into a glass, your thoughts and behavior changing can change how your emotions change.

Like when I walk for exercise, I moan and mope and whine mentally the whole walk lol. cBT the therapist may say well, as you walk look for something beautiful or interesting every few feet. Focus a lot on the sparrow you see, or the flower.

Then because I change my thinking, my emotions change too....I am not complaining whole time, and instead I feel happy

Anyway...most therapists use combo of several types therapy. I am getting rambly lol. If you go therapist
Ask what methods they will use to help you. Talk to therapist about being scared to start therapy, see how they talk to you about that. If you do not like therapist, try someone else.

I will add therapy is not always comfortable, not sunshine and flowers, but it is not intensively traumatic or deeply scarring. Helps you look at trauma or moods etc so that is uncomfortable and can stir up bad memories. But you look at past trauma with your therapist as an ally and helper, and dealing with the trauma mY be uncomfortable to start with,but good therapist with any method does not force you into areas you are not ready deal.with.

Hope that helps!
