Some sibs feel lonely. Your sib may be going to lots of doctor’s appointments to work on getting well again, so they may be around less. Sometimes teens with head injuries change a lot after the accident. It’s almost like they’re different somehow. Maybe you feel like you lost the sib you had before the accident, and you’ve got a different one that you have to get to know. This may leave you feeling lonely. However, if you look closely you will probably be able to see some things about your sib that haven’t changed.
