Welbutrin is a pretty safe antidepressants (atypical I think). It's often paired with other antidepressants. Lamictol is actually an antiseizure med, but it has been shown to be successful at treating BPD mood swings. Don't know what Latuda is. Trazadone is an antidepressant that helps you sleep. Xanax is for anxiety. Doesn't sound like a weird combo.

I take prozac for depression, lamictol (lamotrigine) for mood swings, ativan as needed for anxiety, and ambien as needed for sleep. So I have a similar combo.
