Is it possible?

Medics say the symptoms are not from the hit because I didn't get paralized/insensible limbs or didn't lose consciousness, but rather somatization. But I've wait a month and I'm still with most of the same symptoms, and I've never get before these symptoms although I've had stress many times.

I only can feel some some cheerfulness and anxiety, but I'm sure I wouldn't get sad if my parents die and I don't get emotional regarding anymore from reading. I also got some early awakening insomnia, difficulty to read (slow), headache after reading and befor sleeping and memory lapses. Only slow reading have disappeared after a month.
