[Nostalgia] {...}
Nostalgia is that feeling of remembrance, a thought, a memory of something you forgot about but remember how much you loved it. It's that feeling that can bring even the most serious of people back to a happier moment, a moment to bring back those times before change. Though where nostalgia gives, it's easy to over indulge in it.
It's that dopamatic high, a feeling of pure bliss that you don't want to go away and when it does your body craves more. You start to withdrawal, so you take more and more to keep a flow before you begin to find it's no longer working. Resistance is built to a point it begins draining you more and more rather than helping; clinging onto it like a parasite. Until... you no longer have it.
Nostalgia is more than just a feeling, it's the crutch that drags you along; always reminding you of what you miss in life.
