Anxiety in public places

ive always been anxious going to public places. i feel physically ill and usually i get lightheaded and i overthink and feel worse. i was at the mall and i felt a bit bad but i tried ignoring but then it strated getting worse and i felt lightheaded while standing so i sat down but i kept feeling worse bc j thought ppl noticed and i thought they were all staring. i think i was hyperventilating. i wanted to leave but my dad would not listen and bc i was so desperate i felt worse and i stood up and my head felt heavy and i thought i was going to pass out but as soon as i started walking out it started going away. that happened in class the other day too. i started feeling anxious and kightheaded and the more i thought i couldnt leave and get out, the worse it got and now im scared to go to school or anywhere alone

Did you see a doctor for your problems?
