How Can Anxiety Disorder Along With Depression Be Treated?

I had been suffering from Agoraphobia, Anxiety Disorder since from my childhood. I thought i was born to be like this and i should overcome these fears myself. But I couldn t do that. Last year i realised that it was a mental illness lacking serotonin in my brain and it needed to be cured. I discussed it with my friend. And he motivated me to visit to a good psychiatrist. But i was afraid to go. First day when i reached to the hospital, i had to fill a form to get consulted. I couldn t even ask for a pen from any body. I was so shivering. And i left and returned home. I told my friend again and he motivated me again as well to go and tell everything i suffer with. So i had a visit to a psychiatrist. He said i was going to be okay. And i was like crying real bad. Its been 6 months since i am on medication. The medication started with PXR 12.5 with petril .25mg twice respectively. Then when i told the doctor that i wasn t feeling good as much then he added ESCITALOPRAM 5MG once daily. Then I had to change my psychiatrist because of some reasons. Now I have been prescribed Neurica-BT along with PXR 37.5, Petril Beta10. But I couldn t get Neurica-BT from any store. My symptoms are as follows: Difficulty in concentrating Nervousness Slurred speech Mind goes blank Aggressive mood Irritation with out any cause Lacking Coordination Difficulty in public dealing Don t know how to react Guilt Overthinking Overwhelmed Emotional imbalances Embarassment Thinking that Everyone is staring me Worthlessness Negative thinking Confusion
