Presentalgia 

PRES·ent·AL·gia
noun
a. An urgent desire to remain in the present moment in order to savour, capture, and store every moment of love, joy, and meaning.

b. Presentalgia stems from an acute awareness of how time speeds up that evokes a careful and deep longing to pause in the moment, and freeze time.

c. To bluntly reject the promising embrace of nostalgia and yield to the present moment; enveloped in an intoxicating joy, togetherness, and health surrounding all things and beings to be loved by, and to love.

**Because life is all too short**

"I don't want to listen back to recordings of my time with my family and friends with nostalgia. I want *presentalgia*-- to feel that very same feeling while it's still there, together, happy and healthy." ~S.B.K.

Prestalgia 

To predict the nostalgia that will come from something that hasn't happened yet or that is happening now.
Like missing someone before they're gone.

- You know, once you guys are living in London, I'm gonna come visit you and we're gonna look back on these years and say those were some pretty awesome times.
- Ya, I think I miss this already.
- Me too.
- Aw, I can't take all this prestalgia.

Prestalgia 

Prestalgia is a similar feeling to nostalgia. It's not for a time that's been in the past but rather in the future. You already feel nostalgic about these moments and you know that you'll be nostalgic about them long after they've passed. You can also be prestalgic about a big dream.

"Bro I feel so prestalgic about the trip to this pacific island. It will be something so special. Flying there in that small plane during sunrise, looking at the stars with my girlfriend or eating breakfast at the beach."
"Man that even gives me chills"

or

"If I'm done with university I really wanna do a trip through south america in a little VW Van. Just travelling and experiencing all these beautiful scenerys. I feel so much prestalgia thinking about that.
