My story with social anxiety

It has been 4 years since I started suffering from social anxiety. I noticed during my class study sessions I had trouble communicating with my teachers. It happened because I could not get along with my class fellows. It was unintentional. All my class fellows had good grades in their subjects but I had below average. I was extremely embarrassed. I could not tell and share it with anybody because I had regrets that I wasted lots of my precious time. My whole family was blaming me. Also I had screen addiction. I actually had no idea what was happening at first, it was just an emotion. Then it also started to disturb me mentally and physically. There was a time when I used to feel like I had no control over my body and mind and whatever was happening to me unconsciously. During my lecture I could not sit properly. I could not pay attention to my lessons. My teachers used to think that I had no interest in studies or that I was doing it on purpose, but they had no idea what I was going through. All of a sudden I used to get panic attacks. I felt like my chair was shaking, that I was getting controlled my someone. I got chills, cold sweats, increasing heart rate and red face. People around me thought I was not serious. A few laughed at me and I felt ashamed. My sisters were like girl, you are wasting time and money of your father. My siblings changed their attitude towards me. Problems increased and I left my studies for about 2 years. My family unintentionally hurt me badly. I wanted to get help. I wanted to consult a psychiatrist but I had no money for that, plus my elder sister suffered due to schizophrenia since she was 16 years old. At that time I was 3 and a half years old and now I am 23. I noticed symptoms at the age of 19.
