Is this some kind of disorder?

Since I was a kid I’ve always been very shy. Like EXTREMELY shy. To the point where I would shake and cry about going to school, socializing, going to birthday parties wether it be friends or family. As I got older it worsen. The shyness turned into nervousness and paranoia. As an adult. I don’t get shy any more. But the nervousness is still there. I shake and panic. When I’m surrounded by a lot of people and there’s 5 different conversations going on I can’t hear my self think and I get moody and spazz out. Like for instance. I’m currently going through a divorce. So I had to be forced to move back with my grandma where my mom lives and my aunt. And occasion my sister and my niece come and stay a few days. My family is very loud and they argue for everything idk if it’s old age. But anyways. At dinner today I was the last one to get my food and I was in a great mood. Despite my separation and divorce. So I’m sitting at the table the tv is full blast, my grandmothers talking on the phone, my aunt is yelling Bc someone moved her purse, the baby was crying , and someone in the kitchen dropped a pan. I instantly got so moody and started to panic. Is this some kind of disorder? Should I go to a doctor about this? Can someone help?
