I have been facing this problem since 4 years but since 2 months it has increased a lot ..my day to day activity is affected and I get scared even whensomething small happens or even when I hear a sound .. it's actually making me sick ..I always feel negative ...bad things happening in mind always ..although I m under medication but still it's there ..sweating and palpitation.. so difficult to explain the feeling ... I am not able to concentrate on anything ..I have started running to keep myself fit and eliminate this problem ..under nexito 15 mg and clonazepam 0.5 mg ..so scared of even small changes .
