Nostalgia

I find that nostalgia is the one word that describes my 20s. Every year my life is nothing like the year before it and I cant help but feel nostalgia for what has gone by. I am ofcourse grateful for what is here now, I wouldn’t change it, but for some reason that feeling of nostalgia is always there, sitting somewhere in the corner. Nostalgia for my childhood, nostalgia for my highschool years, even nostalgia for a year ago, or this last summer. I think what I miss the most is the person I was during those times. But does that mean I’m not being present with the person I am now? If i’m happy with my life now, which I am, then why do I miss the past so much? I’m looking forward for what is to come, but i don’t feel ready to really let go of what left.
