Back story: Was on Zoloft 6 years ago for GAD and took it for 2-3 years and eventually got off it. Last 3 years have been anxiety med free. Dec. 27th came down with mild case of covid and along with those symptoms my anxiety came flooding back. I got first dose of vaccine Jan. 17th and started back on Zoloft (25 mg) on Jan. 27th and took 25 mg for 3 days then upped to 50 mg for 2 days and was in ER for palpitations and discontinued zoloft. Then was giving Mirtzapine (5 mg) Feb. 3rd and took that one night and discontinued because first night was awful. Then my psychiatrist wanted to get me sleeping so started Trazodone (25 mg) on Feb 10th and am currently still taking that. March 3rd was put on Buspar (5mg) and took it for 6 days until I landed in the ER for burning sensations and internal vibrations and discontinued that. Was put back on zoloft (25 mg) by a different psychiatrist on March 17th and took it for 4 days but internal vibrations got worse and moved to my head and I can't sleep. I've taken trazodone, gabapentin (1 week) and melatonin in past 3 months. are these sensations/vibrations from getting on/off all these medications? Is it withdrawl? chronic anxiety/stress? lack of sleep? or is it all covid and do I start another anxiety med/sleep medication because I can't heal if I can't sleep but anxiety/these sensations are keeping me up all night and my days are miserable. Any help/advice or if someone has gone through something similar helps! Thank you if you read this far/respond. (Side note: Am 26 yrs old and was previously healthy besides anxiety/depression and life has flipped upside down)
