Hello Friend, Good that you are seeking a help. As you had mentioned about the previous treatment and recurring problems, it's clear that your medicine had only suppressed the problem and not cured it completely. So this time, it's better to take a solution for permanent cure. First, you need to really understand the reason for the anxiety and work on a therapeutic treatment than simply medicine. Alternatively in ayurveda terms, anxiety, sleeplessness, nervousness, appetite issues, constipation etc are symptom of imbalanced air or Vata energy in body. You may consider ayurveda solutions to recover. There are home remedies, lifestyle routines change and few massage therapies cure this. If interested, consult me for further evaluation and recommendation.

Anxiety is treated with medicines and counselling. Are you still taking medication? Sleep disturbances are often secondary to underlying psychiatric disorder.
