You gotta learn how to surf it as best you can.

I'm not being flip. Anxiety, depression and all the related issues, they have a certain tidal nature. There's highs and lows. The key to living with it is to ride the worst waves until things settle back down a little.

If you ignore it, you get swamped.

Doesn't really matter what methods you use to do it. Breathing, meds, exposure therapy, CBT, yoga, whatever. You practice them when things are good, so you can stand on them when things are bad and make it back to shore.

I gotta warn you though, anxiety that's induced or worsened by chemicals is a shit ton harder to negotiate. You can't rely on your normal inner perception of your self. Normally, once you're used to anxiety, you can learn to recognize when it's going to spike, and that alone gives you some empowerment. But when it's external chemicals causing things to worsen, you can't feel when it's getting better or worse in the same way unless you also get used to that chemical and how it influences your anxiety. Which, seems like a pretty bad idea to keep using something that's making anxiety worse.
