advice needed

Your grandpa love you a lot, and it seems you love him the same. Its really hard when a love one depart, espeacily for us the ones left behind. As living things we each have a special energy that we make, when the passing comes all the energy will evaporate into space and time. Form what you explain it could be that alot of left over energy from your grandpa is still trap within you making his departure incomplete. The energy can be trap with guilt, love, anger, and being too stubborn, either from you or from him. You said that you have try maything that does not wrok, so you could try cleansing yourself. Meditate and say your good bies with you grandfather, and tell you self that nomatter where we are we are always together and onday we will meet agian. Oh and one more thing try talking to him and find out the reason why hes is back.
