Hello, I would like to clarify some doubts. I am 21 years old, and a few months ago I began to feel very tired, anxiety, stress. One day I got up with a little breathlessness, so my heart was racing. After that I was never the same. I already had panic syndrome at age 13, but I walked, I ate. I feel more and more weak, I lost a lot, every time I ate in the morning, I had vomiting, from time to time my heart is racing, when I'm not eating, I'm very thin, I feel pain in the back of the neck, especially if I get nervous. I always feel little air, a lot of weakness, pain in the anus, vomiting, I lie down because I feel very weak. I did tests, which I still did not take to the doctor and in my urine gave 19,200 leukocytes, when the normal is ten thousand, and 13,000 epithelial cells. I have never felt so weak and weak in all my life and before I could get out, now I am very weak and thin. I do not know what I have.
Expert answer:

In the urine test has a bit of infection, but this does not have to be with your symptoms that are actually compatible with emotional problems, you can not be sure, but it looks like depression. You need to look for a doctor, you may be a general practitioner, but the ideal is a psychiatrist.
