Anxiety, stress, fear. What should i do?

Dear,  I can understand the distress your are going through. From your complaints it very clearly appears that you are suffering from anxiety disorder, mostly a panic disorder or generalised anxiety disorder. Although it will take a detailed interview and work up to confirm it. Well, the point here is that you ve tried many medicines and still not settled on any. I can see few issues here 1) Anxiety problem cannot be cured only by medicines, although medications are essential to control it but for cure it requires more than just medicines. Hypnotherapy is not useful. Therapies like Graded exposure techniques, behavioral therapies, Cognitive behavior therapy, relaxation techniques, etc are indicated and proven helpful. Psychological therapy a is must if you want cure from it. 2) do not try to find root cause as apparently there is no specific root cause for anxiety disorder. It's like diabetes or high blood pressure, like these have no specific cause even anxiety disorder has no specific cause, it can happen to anyone. Like diabetes of high BP can be controlled with the help of excercise, lifestyle changes, medicine, anxiety disorder can also be controlled. It is stress related, so reducing stress can help you with anxiety as well. 3) I find a lot of scope for changes in lifestyle and healthy daily hygiene.

Consult  a psychiatrist who can do a detailed workup and help to formulate strategies to tackle anxiety.

Do not worry it can be cured and controlled.
