It is a tough situation you seem to be struggling. At the same time it is a very good think that you know your fears are irrational.
Sometimes after you stop medicines , feeling anxious , nausea ...etc can be realised . You should ask the doctor under whose treatment you were.
Anxiety is Intense, excessive and persistent worry and fear about certain situations , which may later develop to unrelated situations .
This needs deep evaluation regarding the situations , your experience , how it was affecting you , your self talks etc....
Self-treatment
Physical activity, a healthy diet, regular sleep and relaxation exercises may all help to reduce anxiety. Joining a support group may also help. To manage symptoms effectively, it's best to avoid caffeine, alcohol and nicotine.
You should seek a therapist
