Parting can be such sweet sorrow, but sometimes it must be done. But what you can say is you're not truly leaving: you'll remain in spirit. This trope is no less powerful when the person is more than "leaving" and is in fact dying or Ascending to a Higher Plane of Existence or similar.
This is common for when the person is going to be away for a long time or if the person the leaving one is talking to hasn't been away from them for a significant amount of time before (the latter is most common if the one being talked to is very young and/or naive). It's also common to have an Always with You moment if the person is leaving and they're not sure they'll be back or even believe they definitely won't be, either because the place they're going to is dangerous and they believe they might die, or if the place is hard to come back from (another planet, another dimension, a lifetime prison sentence, etc). Another variation is a ghost saying this to a living person they knew and loved.
There are many ways to do this. The most simple way is to simply say, "I will always be with you in your thoughts/mind/heart", while another common way is to say, "I'll always be with you in here" and point to the vicinity of the other person's heart. A third (less common but not incredibly rare) way is to encourage the other person to liken the one leaving to some part of nature (for example, "When the wind blows, that's me tickling you"). This is more common with the death variation but can be used when the person is simply leaving. If the departure is only temporary, these lines often precede the phrase "until we meet again" or something along those lines. "We can never really be apart" is also a common way of phrasing this, as is "As long as you remember me I'll always exist" for when the character is dying.
How the other person responds may vary. They will usually either become sadder and start to cry and say something like, "No!" or "But I don't want you in my thoughts/mind/heart, I want you here!", or they will cheer up, at least a little, and accept that the departure is inevitable.

- On the Nintendo Switch in 2017, it was discovered that a copy of Golf from the NES, a game programmed by the late Satoru Iwata (who had passed away on July 11, 2015), was hidden in the firmware of every console. The game could be accessed if the joysticks were moved in the same way Iwata had gestured his hands during Nintendo Direct, on July 11th provided that you didn't change the date yourself (otherwise the internal clock will detect the change) and your console had not been upgraded past Version 1.0.0. The following year, the game was removed. In Japan, it's been considered symbolic of an omomori, a small bag left at a shrine or carried attached to something like a backpack as a blessing in memoriam, the bag not to be open lest the blessing be removed. The omomori loses its power in a year and is disposed of.
