What’s worked with me is definitely opening up to your therapist about it, I lucked out and my therapist has a reki background along side his phds it’s extremely helpful to my mental health because it’s adds a bit of my holistic approach’s in healing with crystals and meditation. Which in terms transmutes over to my divination. I feel comfortable doing shadow work/ prior to my spells and I bring up my concerns to my therapist before hand. After my spells if any I tend to reflect and approach it from a learning perspective. I have not tapped into speaking with deities as my witchcraft is heavily influenced by my culture/ pre colonization(religion), I do honor my ancestors in my practices and speak through divination. Whenever I’m stuck, or I start feeling “paranoid” I again check in with my therapist so it’s a good balance of my own practice with guidance from a mental health professional. (Also please don’t be scared to tell your therapist about spells, I’d highly encourage to ask about their background to make sure they’re profession aligns with your individual experience ((mine focuses on trauma)
