What to do if I have neurosis and can I take something for the sinuses for an antibiotic?

Hello. I am 30 years old. I'm in the process of taking cipronex 500mg 2x1 for the upper respiratory tract (it's more about throat pain), I feel that sometimes I have a stuffy nose or something more can be used for this? In addition, during the visit, the doctor diagnosed me with neuroses and I am not able to eat as much as before. In the past I had written emanere 20mg or not hurt as I start taking but this emanere to stimulate the appetite? Neurosis began to manifest itself in the absence of an appetite, discomfort in the chest on the left side , around the left shoulder blade above and sometimes between the shoulder blades, feeling pulling to the armpit, waking up at night, even fear of falling asleep, tingling of the scalp, cheek and sometimes forehead, key in the throat , frequent catching of air. However, the doctor did not refer for any tests even from the blood. He wrote pramolan but again it seems to me that he is too strong. He drinks lemon balm in the evening before sleeping. I suspect a deficiency of magnesium-type vitamins . Will the intake of vitamins (but I do not know what) help with neurosis?
