Hi. Did you stop the medication by yourself or as suggested by your doctor? Medicines should not be abruptly stopped as that can lead to withdrawal symptoms. There is usually a systematic procedure to stop and reduce the dosage, so please do consult your doctor if that is the case. There could be some factors that could trigger your anxiety / panic attack. Counselling can help you to identify those tiggers. Some lifestyle changes, physical activity can help as well. It is important to address it and understand the underlying causes to your anxiety. There can be many reasons, stress at home-personal or professional life, overthinking, anything that's causing you discomfort, any past issues, there can be any and many. It is better to seek counselling and identify triggers to address the issue completely.
Next Steps
Speak to your doctor on the medication and seek counselling. It can really help in your case.
