PLEASE, I'M SO DEPRESSED:Can anyone tell me if the country will get better this time?...or are we doomed??

Well, your grandma is saying what she says because she is using her experiences as a source. From her experience, **** gets ugly and then it gets better. It's always kind of been that way dont you think? I think her answer to you was pretty spot on. of course, no one can predict the future, not her and not others. No one can tell you its going to get better or worse. We never know.
