Hi! I hope I'm not too late

Anyway, mi manchi means I miss you- I need you is 'ho bisogno di te', just for the press.
Here's your translation... by the way there are a few spelling mistakes which I'll correct for you.
Mi Manchi= I miss you
Quando il sole dà la mano all'orizzonte
When the sun shakes hands with the horizon
Quando il buio spegne il chiasso della gente
When the dark switches off the hustle of people
La stanchezza addosso che non va piu via
The tiredness inside me that won't go away
Come l'ombra di qualcosa ancora mia
Like the shadow of something that's still mine
Mi manchi
I miss you
Nei tuoi sguardi
In your looks
E in quel sorriso un po' inconsciente
And in that slightly cheeky smile
Nelle scuse di quei tuoi probabilmente
(Are you sure this verse is correct? I can't find any sense in it sorry)
Sei quel nodo in gola che non scende giu
You're that knot in my throat which won't go down
E tu e tu
And you, and you
Mi manchi mi manchi
I miss you I miss you
Posso far finta di star bene ma mi manchi
I can pretend I'm ok but I miss you
Ora capisco che vuol dire
Now I know what it means
Averti accanto prima di dormire
To have you next to me before I go to sleep
Mentre cammino a piedi nudi dentro l'anima
While I walk barefoot inside my soul
Mi manchi e potrei
I miss you and I could
Cercarmi un' altra donna ma m'ingannerei
Look for another girl but I would be fooling myself
Sei il mio rimorso senza fine
You're my endless regret
Il freddo delle mie mattine
The cold in my mornings
Quando mi guardo intorno
When I look around
E sento che mi manchi
And feel that I miss you
Ora che io posso darti un po' di piu
Now that I can give you something more
E tu e tu
and you and you (you is the subject of the verb 'manchi' in Italian because literally it would be 'you lack from me' so you is the subject)
Mi manchi e potrei
I miss you and I could
Avere un' altra donna ma m'ingannerei
Have another woman but I would be fooling myself
Sei il mio rimorso senza fine
You're my endless regret
Il freddo delle mie mattine
The cold in my mornings
Quando mi guardo intorno
When I look around
E sento che mi manchi
And feel that I miss you
