None of that is a sign of a good professional. It basically means "If your problems become too severe I won't deal with you anymore because I don't feel I have the skillset to handle it". It shows an insecure therapist who lacks confidence in their own practice. Not to mention, it's actually dangerous for her to inadvertently punish you for taking a certain medication that might be very beneficial to your journey and it would also be incredibly unethical for her to abandon you during a crisis. It's always up to you who you see but she sounds like a bad egg to me. I can't blame you for trying, though, my area is very dry of good therapists as well.
