Why am i feeling depressed after severe eye trauma?

Could be a : Situational depression, but given the fact that you suffered severe injuries to your eye, my guess is that you may be developing post traumatic stress disorder with depression as a result. Either way, you need to be evaluated by a psychiatrist and also see a psychologist for psychotherapy. Best wishes and i hope that you can make the necessary adjustments to lead a happy and meaningful life again in spite of the injuries.
