Hi thank you for posting the question. I can see that you are only 20 years old and appropriately worried about taking medication long term. Your question gives answer on two fronts. 1. Medication like paxidep control the symptoms and may not be a cure. In my practice I combine psychological therapy with medication. Once you learn skills to overcome anxiety paxidep can be stopped slowly.
Next Steps
consult a clinical psychologist and learn skills e.g. cognitive behavioural therapy. Go for regular walking, healthy diet and sleep well. don't stop medication abruptly.
Health Tips
focus on relaxation and physical fitness, continue treatment and get psychological therapy
