Can anyone help???Panic attacks' problem....?

Ok so im a 16 year old guy that has panic attacks. When i was young (about 8~) i had a six pack, the i moved to the united states, on the first day of school i didnt know any english so everyone was making fun of me, but i didnt care, because i knew they were just little douche bags. When my homeroom teacher showed me around the school and tried meeting me to all the teachers i wanted to cry because i didnt know how to say anything and everyone was pretty much making fun of me ( i was about 9 back then) so then i gained a lot of weight, people called me fat, then i lost a lot of weight (was almost annorexic) and now im working out (taking care of myself) but im ugly as **** because of all the "unknown" stress. 2 days ago i had confirmation, everyone was in a room, waiting for 30~minutes, my face was soo red that it wasn't even funny...when i dont know anybody and im alone with them i get really shy for some reason, and that really pisses me off because i cant control it, also when im presenting a project in front of my cl, my face gets so red that i just wanna punch myself as hard as i can in my face because like i said before it pisses me off, i dont wanna be shy, im not a shy person, at least i wasnt back then...so my question is how can i avoid getting panic attacks? are there any pills for that or excersies or ANYTHING....i will do it, thanks for everything guys, cya
