Immense fear of dying.

I think about death a lot, more than I should probably. It terrifies me. I believe in god and heaven but I just get so scared about just not living anymore. Not waking up to the life that I love, not talking to my man or family or friends, everything just stops. I just don’t know how to distract myself from these thoughts. I know that death is inevitable and heaven is wonderful but for some reason I still have this fear. Help!!!
