Need support - anyone else have a highly sensitive, high anxiety child?

hello, i am a 12 year old child who has been suffering with severe anxiety since i was 8 years old. it usually happens with an event like you said, and mine was me vomiting and getting severely sick. it lasted until about last year and caused a lot of trouble so i suggest that you go to a therapist immediately and try to get him help. but don't make it traumatic for him and always make sure to be on his side.
