Lexapro to Prestiq

Man this has been a wild ride and I need some success stories and possible advice. I'm (30M) have been on Lexapro 20mg for about 3 years. I originally started it for GAD. I have severe anxiety all the time about little things and constantly have panic attacks. Lexapro really fixed that for me. It stopped the part of my brain from "creating fake scenarios and getting anxiety about it". I found myself thinking more straight and not having such terrible intrusive thoughts. I remember I would freak out about EVERYTHING. How people treated me, looked at me, ignored me, and it constantly sent me into anxiety attacks. The Lexapro helped that a lot. But I still had occasional anxiety but it was manageable.

These last 3 months I went into a deep depression. (I would've never considered myself depressed before hand) After battling for over 2 months I finally broke and went back to a psychiatrist. She recommended that I cut my 20mg Lexapro in half to 10mg for 3 days and then quit cold turkey and start Prestiq 50mg. I did, however the very next day I had terrible anxiety. So I decided to continue taking 10mg Lexapro for about a week with my 50mg Prestiq. Hoping it would help anxiety while Prestiq kicked in. I woke up yesterday after a week of doing this with EXTREME anxiety, fatigue, and what I can only explain as my body vibrating. It was impossible to leave the couch.

Last night, I decided to stop Lexapro all together because I'm worried about serotonin syndrome. Today I still feel like I'm vibrating, I'm fatigued, and I have anxiety but not AS bad. I truly feel my brain and body did not like that mix at all and after doing a lot of research, I now see why my doctor wanted me to quit cold turkey and go straight to Prestiq. But now I'm terrified my anxiety is going to come back without Lexapro. I've read so many success stories with Prestiq but how is it with anxiety? Panic disorders? I've read that it's not truly used for anxiety but then I also read success stories of people saying how well it helped their anxiety, panic attacks, and depression.

I've been researching so much and I feel like the more I read the worse it gets. Does anybody out there have a similar situation to me? Any advice? Success stories for anxiety?

It really confused me that she took me off Lexapro knowing it helped my anxiety so well and just put me on Prestiq. I fear the depression will go away and the anxiety will be full force again. I also have POTS which is its own beast! I have POTS, GAD, MDD, and PTSD. I'm hoping Prestiq will be that magic cure all medicine but I'm having huge doubts. Mixing both Pristiq and Lexapro sounded good but it's destroying me mentally and physically. I'm terrified about not having Lexapro while I wait for Prestiq to kick in considering every says 4-6 weeks until it truly does it job.

I work full time and I can't be like this. Any advice? Thanks for reading my rant. I've been falling through the rabbit hole of reddit about this and figured screw it I might as well make my own post. Thanks for reading.
