What is the difference between "get" and "go" when expressing states?
For example, "She is getting crazy" vs "She is going crazy".
and "I'm getting online to check my Facebook" vs "I'm going online to check my Facebook"?
According to my research, it seems that "get" can be used for both positive and negative feelings, for example, "she is getting upset" and "she is getting excited".
And "go" is normally used for negative feelings, for example, "She went insane"
However, "go online" doesn't carry native meanings.
Also, "get" is often used in continuous tenses and "go" might not be used in continuous tenses, but I am not sure.
Finally, I think we can only remember phrases by phrases, there is no way to make sense of them.
