Anyone actually satisfied with adding Wellbutrin to Effexor or another SSRI/SNRI?

I’ve been taking Effexor 150 mg for anxiety for about 3 years. My anxiety is mostly under control, but I’ve become indifferent to almost everything.

Talking to people has started to feel pointless and meaningless. I’ve withdrawn into myself and become increasingly intolerant toward people, discussions, basically everything.

I can’t even focus on watching TV shows or movies anymore.

Has anyone had success adding an extra medication like Wellbutrin to deal with this?
