psychiatric condition if...? The day after my mother ends up in the hospital my brother e-mails me with this:

[[[[[["If you must think of her (that old fantasy) just think of the name Gally. After all she was a gal wasn't she?
I hope you don't think I'm just trying to be funny or something but I do think that some thing like that can be kind of important to keep around until you are really done with them.. even though I also understand if a person such as yourself can and does appear to have more going for themselves these days.
Right Between The Eyes Gally
I'd hate to see you lose something just because Shawn antagonistically took the Alita name".]]]]]]]]]]]]

This guy he refers to I guess changed his name.
I don't even like Comics.
So, what?!
Our Mother should be the priority.

What does anything on the e-mail refer to me or the reality of our mother being in the hospital? We have not even gotten around to planning a visit.

When I got out of the Hospital the guy treated me bad

It sounds like he sent the email to the wrong person. It's out of context with what is going on, and doesn't seem to make much sense. Send him a reply with the original text in it and ask him: What?
