I believe you should wait another month or two at least. Partly because of the date you said you had your accident, October 2015. That is still a month away. Just looking at your head I would assume that you suffered a pretty bad concussion. The longer you wait for your brain to heal the better off you will be. The safest and best thing to do is ask your doctor this question, because he/she knows the damage that was done.
If you do decide to go without getting a thumbs up from your doctor please keep the dives shallow and as always go with a dive buddy.
