Having your third eye open is a gift and i suggest that you try to learn to use it to the best of your ability instead of closing it. I myself am learning to cope with my third eye, ^your family is dead, right?
I do not suggest you close or shut down any of your chakras as this will throw you out of balance and may cause worse affects. Better that you learn to control it and block it out. Your family members may be attracted to you simply because you can see them.
