Am I in a crash?

I have a UTI and am hypersensitive to medication, so I decided to try treating it with d-mannose instead if antibiotics. As soon as I took it, I developed the following symptoms: - heart palpitations - tachycardia - tingling hands and feet - tinnitus - brain fog - labored breathing

I only got two hours of sleep, and the symptoms are still present more than 12 hours later. Is this a crash? An adrenaline dump? Something else? I'm scared to take more meds.
