Thinking about talking to a professional about ESA letters

I’ve been dealing with anxiety for a while, and my cat has honestly helped me through some rough days just by being around.

Recently someone mentioned that emotional support animals can sometimes be recognized with an ESA letter if a licensed mental health professional determines it’s appropriate.

While researching the topic, I saw a service called My ESA Therapist that offers evaluations with licensed clinicians. I’m wondering if anyone here has experience with that process or has spoken to a professional about it before.
