Brain Zaps and Migraines. Please advise!

I'm 24. I was on several antidepressants, anticonvulsants, mood stabilisers, etc from 2021 August to 2022 December post which I stopped taking them. I have had episodes of severe anxiety wherein my brain gets extremely foggy, and I get something which is more or less like a mini-seizure. I start shaking, stuttering and say gibberish. Even if I try to make sense, I am unable to speak. Secondly, I have been experiencing electric shocks in my brain that feel like thunderbolts or very loud drums and are debilitating. They don't hurt but they immobilise me. It comes and goes in 30 second intervals and sometimes is accompanied with a ringing sound in my ear (both phenomena are distinguishable and occur simultaneously) I also have increased migraines and insomnia. Although, the insomnia seems to be triggered by more a phobia of sleep than much else. My own psychiatrist suggested Propanolol, and it helps a bit. But I don't want to be on any antidepressants again. Please advise
