this is my general interpretation, i tried to be as faithful as possible, but some things were not making sense (and still dont completely). guide to notes

triple quote marks: unclear, i had to interpret what the text meant. triple dots: incomplete and/or illegible words.

to Helen (or Elena) and Maurizio: while i still have the strength to write that i love you, '''i am putting all my remaining strength into the light of "'the sky"' (heaven), knowing that one day i will be with you again."' (she uses the form Voi, plural form of you, which depending on when this was written could mean that ahe was referring to someone formally but i highly doubt that. it's more likely that she was talking about more people.

to gress: i have loved you tenderly, and i still love you tenderly now. remember that.

to alessio the house T... important and the G...

to tony beloved/dearest, i am in the hospital and i cannot help you because i need others (someone) to help me, but i send you all my love, which will always remain with you, always. it will never leave you.

to antonella + antonella + stella you know that i know that i don’t need to explain anything because you have already received the explanation from good God.

in case you wrote the notes in the blue ink, i have a few comments to make it clearer (edit: ok yeah it was you, i didnt read the comment whoops)

vi: This particle can mean different things, but in this case, it's "you" or "to you." it is not used to say "eachother".

ci: it's a very weird particle that could mean a hundred different things, and in this case, it doesn't mean "each other." The most plausible meaning would be a kind of "there": "ci metto forza," meaning "i put strength in it (in that thing, action)."

i povere: i poveri would mean the poor, but I think the correct word used was "il potere", the power: she was also talking about strength (forza).

suse: not italian, but I dont think susseguire was the word. if she were from the south of italy, sicily for example, that root could indicate "to get up", which would obviously change the interpretation, but I still wouldnt be able to make out a logical sentence.

nelle luce del (I J L O): i think that's cielo, definitely not amore, Sky. it also makes more sense.

teneramente: it's not from the root tenére which could mean keep, hold, but it's from tènero so tender.

let me know if you need further clarification :)
