"Childhood memories" in French?

Childhood memories .... Is this text correct?

• I am an Italian boy and I do a text on the memories of my childhood, I wonder if this text is correct ...Thank you.... Thinking of my childhood memories that I have so many come to mind ... First I remember my first day of elementary school where I cried because I did not want to be alone .... but what was even better was to come home and have no worries. Every afternoon I went out to play with my friends and I came home only when it got dark .... Well ... I think about those happy hours Giori and wonder what I miss most of the fantastic time .... I miss all the absence of problems since the first My only concerns were the cartoons, but also the happiness I felt when it was Christmas, especially when I waited up late gift from Santa Claus ... but certainly the best thing was to dream and fantasize with the mind without limits ... Now this is gone, and everything leads us to make complex unnecessary, when in fact the only problem at that time was to finish the album of the figurines.

• Answer:

  Thinking back on my childhood memories, I have so many that come to mind. Firstly, I remember my first day at elementary school. I cried because I didn't want to be alone. It was when I came home that I had no worries. Every afternoon, I went out to play with my friends. I came home when it became dark. I remember those happy moments with Giori. I sometimes wonder what I miss the most about this fantastic times with him. When Christmas came every year, I remember feeling excited and I knew it was truly Christmas. I loved the feeling of opening presents from Santa Claus. But certainly the thing I remember the most was having a mind without limits. An imagination of fantasies. Now this imagination is gone, everything is unnecessarily complex. The only thought back then was to finish the collection of album figurines. This is my version. I missed out "miss all the absence of problems since the first My only concerns were the cartoons". I didn't really understand that sentence. Just try not to overuse ',' and use '.' instead. Also, your use of '...' was excessive. Other than that, it was pretty well written.
