I'd she is noticing problems she should not ignore her mate, she should not get involved with her new friends and especially if she doesn't trust them, and she should not forget about her problems because they could mean something NAD or even worsen hurting Jamie and/or even others. Thia leaves the last one which is a smart choice. If you ever notice something wrong or different in a person to the point where it could do harm ALWAYS tell an adult you trust so they can help you and your mate do the right thing.
Depends on what you think but they can be a dessert
True. If you look at when doctors do CPR, they usually perform CPR when there is no breathing and/or no pulse. Think of CPAP machines. They force air into the lungs when someone stops breathing in their sleep (sleep apnea). Hopefully this did not confuse you.
