Sorry to hear you're struggling with the challenges meds can bring about.
Purely from an energy perspective, anti depressants are know to reduce energy levels in some cases. Seeing you've reduced the AD med, could what you're feeling actually be a massive energy spike? Perhaps something to wonder about.
A friend of mine who stopped her AD meds faced a pretty significant challenge in managing her new high energy levels. She also faces the challenges which comes with a highly active nervous system at times (anxiety) yet she's gradually learning to manage through channeling and understand the energy spikes. Breathing and grounding exercises have made a positive difference to her. Meditation is something else perhaps worth considering. There are some guided meditations out there which can lead people to meditate on calming their systems down naturally. Bit of a search on YouTube could connect with with one you vibe well with.
So, the question could be 'Has your nervous system and other systems become hyper-active after being suppressed by the meds you were on and this is what your feeling?'
Just a bit of food for thought. Hope it helps.
Take care :)
