If you know people who are suicidal, or if you know people who are bipolar, depressed, have panic attack disorder, just be there for them. They're going through something that's very, very hard.
A lot of times I feel I probably would have ended up in a mental hospital if it weren't for the structure that 'Bones' gave me.
If you have a friend or a family member who's bipolar, or has panic attack disorder, or is depressed, read up on it a little bit so you can get to know where they're coming from.
