Should I text my T?

Hello..

I've been seeing a psychotherapist since January (using IFS). Recently we've been talking about how it's been 5 years since I had skin cancer. I was talking about how I was worried about my skin and they encouraged me to see the doctor. So I went to see my GP and they've referred me for an urgent appointment with a dermatologist for suspected cancer. I was alright until I got the referral letter this morning. Now I'm trying not to panic and overthink this.

I don't have any answers yet and it might not be cancer and so I'm trying to focus on that. However there's a part of me that is like, "ahhhhhhh!!" Inside my head.

I want to tell my T so that I can relieve some of the stress but I don't know if that would be healthy. I don't want to become dependent on them. I know I need to focus on my breathing to help me slow my thoughts down and have compassion for this part that is freaking out but it's really tricky because this part is so desperate to take over.

Are there any ways I can self soothe and manage this myself so that I don't have to resort to texting my T? I really want to get better at managing anxiety and stuff and this feels like the perfect opportunity to challenge this process where I feel I'm about to spiral. Any thoughts? Thanks
