People usually stay close to the loved ones after leaving the physical body just to see they are doing ok and wanting usually to give some signs to them to show that everything is just fine there. So it is very likely you have this person near.
If you want a contact, you need to know that when you are deep in sorrow, it is difficult to pass through your energies and give you signs or messages so try to be in good mood and calm with emotions even for a while so it is easier to talk to you or give you a sign. you can also ask him/her come to your dreams. Dreams are not always imagination but we do experience life outside the body. This is the time to meet the loved ones passed away as well so ask that and be prepared to have nice dreams. Those dreams can be symbolic as well, but it will most probably come for you as you ask.
Good luck and lots of peace and love
