Concerned About Stopping Anxiety Medication - Need Advice

Hi everyone, I'm feeling really worried and frustrated. My doctor suddenly stopped my prescription for my anxiety medication without any warning. It was supposed to be refilled today, but they haven't gotten back to me at all. I feel like there's been a misunderstanding and I'm not sure what to do. Does anyone have experience with stopping this kind of medication abruptly? Should I be concerned about withdrawal symptoms? Is it dangerous to stop taking it so suddenly? This is my first time posting here but I've been following for a while. I really appreciate any advice or support you all can offer! Thanks in advance.
