Hi... The anxiety you are experiencing is purely cognitive (as you have explained) and Cognitive Behaviour Therapy (CBT) is the right treatment for it. Medications are not a long-term solution in such cases. Our brain adapts to external substances, including anti-anxiety/anti-depressant medication. Medication is useful more in cases where the root cause is more genetic/biological in nature.
Next Steps
Start taking Counselling Sessions from a Psychologist. Consult a Psychiatrist if you seek medication.
