Many of us heal slowly or incompletely.
Do everything you can to help your head heal. But also let go of your expectation of returning to the old you...it might not happen. Move forward, except your new self and try to manage the symptoms.
Good luck
Reading on this board can teach you a lot. In the beginning I came here looking for a quick fix...now I come here knowing that the people here have a wealth of knowledge and understanding.
