I differ from the view taken by @shriks
When your advocate applied for Anticipatory Bail at Sessions Court, you are required to wait for the formal verdict. It happens in certain complicated matters that the judges reserves the orders. It may also happen that the judge may be on leave and that is delaying your orders further.
I suggest you send a relative or a friend to the court office and find out if the judgement on your bail application is released or not. If not, you may inquire from the concerned court staff like reader etc.
As far as your application to High Court is concerned, you may approach High Court only when you have an order from the Sessions Court which you wish to assail. High Court may take as much time as it may deem fit to decide your application. There is no bar on time within which a court is required to conclude the case. If in case the court does not grant Anticipatory Bail immediately, it may still put a "stay on arrest" till the pendency of your application. This would protect you from arrest.
All the best!
