Hello and thanks for your query. I understand that you are going through a very distressing time. From the description of your symptoms, it appears that you have had a severe panic attack. It is likely that the excess of Cocaine you had taken had triggered the episode. Now, you have mentioned that you are still going through very distressing symptoms and that despite taking Valium your symptoms have not subsided. In this case, the best option is to see a doctor for further treatment. You need to go to the ER and report your persisting symptoms. In such severe cases of panic, a parenteral (injectable) medication may be required. You also need to be checked to see if your symptoms are not due to any other serious medical condition because it is unusual for a panic attack to last this long. If you can t go alone, please ask a friend or a relative to take you to the ER. In the meantime, you can try practicing relaxation techniques like deep breathing, progressive muscle relaxation, yoga, etc. to try and calm yourself down.
