Please help

I’m 28f so I took Paxil for ppd and ppa I started from 10mg to 40mg but I was still dealing with anxiety so I switched to Paxil cr 37.5mg in like 2 months on this dose I got stable. I was almost a year out ppd and ppa so I thought I could get off Paxil cr. I went from 37.5 to 25mg for a month then 12.5mg a month then zero. Had terrible withdrawal went back to 12.5mg helped with withdrawal but anxiety was still there went up to 25mg. I’ve been on 25mg for 3 months . I definitely see improvement I did get better but anxiety is still there chest tension it isn’t as intense as it was but it’s still there. Mood got better but still down. My sleep is still bad too I wake up 2-3am and wake up early like 7am I get like 5-6 hours of sleep even thought I take Paxil cr in the morning. I think it’s a cortisol issue cause as soon it hits 8pm I’m normal no chest tightness no anxiety. So I went up to 37.5mg my doctor told me that’s the dose I got stable on so I did. I’ve been on 37.5mg for 2 months and I got worse. 3 weeks ago I started experiencing brain zaps, headaches, head pressure, neck spams and shoulder tension. Brain fog and memory issues I’m going through hell and I don’t know what to do please help me what should I do? I’ve been looking into neurofeedback will that help? Or anything else please help.
