From last three months I am having pressure on my ear. Shaking body if I worried too much or in fear. Once my bp was 140-90. My heart was pounding and tingling in hands and feets. After that my mind is become weak and I am scared to go outside and if I try I become very fearful and again symptoms develop. Is this mental illness or something else. Sometime if i feel tensed everything look blackish and pressure on my head.
