The best analogy I can think of is to imagine going on a diet tomorrow and expecting the weight to have all gone by the next day. It takes consistency before you can read into whether it’s working.
I would stick with your Zoely to suppress your cycle with the knowledge that you will feel worse before you feel better. If you feel worse it’s a good sign something is shifting. If you didn’t feel anything it may not be doing anything.
As you know, antidepressant withdrawal, even done with the finest titration, will be sending your nervous system all over the place. However, again, it’s a sign things are shifting in the right direction.
Try to picture all of this as travelling in a car on a very bumpy road that is taking you to where you will finally feel balanced. Enjoy the ride, reframe the adrenaline as moments of joy. Put some music on, dance, put a scary film on, scream! Matching the adrenaline will help you to ride it out.
You could also chart your moods a few times a day in a diary, then compare them every week and you’ll start to see the subtle changes as they happen.
Have fun and enjoy the ride!
