Sinus headache/Fear of speaking

I am a 32 y.o. female; suffer from chronic sinusitis since the age of 13. I had a sinus/deviated septum surgery a year ago and since then, I can freely breathe through my nose. Before the surgery, the main symptom was a blocked nose. However, only recently, I began having headaches like I used to have during an acute sinus infection when I was a teenager. The pain is between the eyebrows, also painful I when apply pressure, especially the left side. Pain is the worst in the afternoons (~ 12-4pm). Applying something hot to this are helps a little. Left nostril (always and only left) gets blocked at night usually before I go to bed.
Although I consider myself a relatively healthy person, my tongue looks unhealthy, as long as I remember myself. Right now it is mostly whitish with couple red spots and a vertical scratch. Toe nails always break vertically (mostly right toe). Acne on forhead.
I like bitter dark chocolate and ice cream. Don’t like when the food is too sweet or too salty. No aversions to any foods. Prefer warm foods over cold foods, drink only warm/hot drinks.
Hate cold, windy weather, like hot weather.
As far as my personality; from outside, I seem to be calm and patient, a person that never gets angry, not too sensitive or emotional. From inside, I am sensitive and get hurt easily, but don’t show it. Only close people can make me angry, and make me cry. I think a lot and think slowly. My main concern (since childhood) is fear to speak in public. In situations where I have to speak in front of two or more people, I experience heart palpitations; my heart beats so fast and so loud that I have a feeling that everybody in a hears it beating; I loose concentration, my thoughts escape, and my voice changes. When I speak and something small distracts the crowd even for a few seconds, I return to my normal self. Because of this problem, I lack self-confidence.
