That's okay! Some people find that talking isn't as comfortable, so other methods are more useful. I knew someone in this position, and what they ended up doing was writing everything down, like a diary. Rather than having to repeat themselves again, or having to talk through their issues, they found it much more helpful to note things down, and read back through it. The first step is getting it out! It's better to have things written down, than racing around your head.
Much love <3
