I've never been a particularly nostalgic person, almost the opposite... i wanted/was curious to go on

But the last years of my life have been very bad and i lost two important persons (one is my father); so i found myself thinking about the past
Before this, i just used to think about the past sometimes with a jealous eye, regretting some things but then i used to quickly return to the present and think about how to fix and grow... even if, again, in the last two-three years i started feeling discouraged for a mix of factors :/

And now go to sleep wishing that Dr Who could appear and knock at my door to travel back to times where some shits weren't already happened

To better answer the question: i still do not miss the childhood so much because it wasn't all just funny and games...
But since now i wish that i was a better daughter, i miss: the innocence, the possibility of creating something good, and express simple love to my parents and relatives
But i recognize that to have a whole life ahead it's a big thing; one needs to be guided a bit and stay calm
