Microsoft Word Online ^^ maybe this can help, no download, free, saves to OneDrive as you type, if something crashes then you can just log back in on your browser through microsoft (ive had a Microsoft account since ive had Skype for a long time), simple, easy. I use it all the time for school. The only thing is that idk what web browser you use, I use Google Chrome and it works on here but i have no idea if its only for google chrome or if it works on other browsers cause ive never really checked but i dont see why it shouldnt ^^ I hope this helps
Dont worry about us, we are all understanding and patient ^^ so take your time, maybe try this (message me if the link doesnt work) and keep us updated <3
