As you're probably aware, there can be many symptoms when you stop taking antidepressants, including things like depression and anxiety, which lead people to think that they need to stay on them. Hopefully they will wear off soon, it sounds like it's only mild, which is good. With menopause it"s so difficult to try to work out what's what, as for instance I have extreme fatigue and brain fog because of having ME/CFS, which are of course also common in menopause! .
I've found l-theanine with lemon balm, and magnesium citrate from Nature's Best helpful for anxiety. I also do creative visualisation where I imagine I'm somewhere beautiful, riding a horse. Obviously it needs to be something/somewhere that works for you. If I can really get into it, I find it calming. YouTube has some great meditation/relaxation videos. Also I lie down listening to music that I find relaxing, and that comforts me. Hope you feel better soon. 🙂
