Suddenly it seems like I'm going to have a heart attack, or avc, or something, I'm afraid of going bad in the middle of the street, and I end up getting frustrated not doing all my work properly, last exams did not give anything, I'm 38 2 daughters, and I find no reason to accept a possible depression, which doctor should I seek first? I'm already taking rivotril on my own. thank you.
Expert answer:

In fact because of its description it looks more like a picture of anxiety, a disorder or panic syndrome and not a depression, you should seek a psychiatrist.
