Hello everyone, I hope you’re well and thank you for reading . Long story short I’m struggling with Sever anxiety at the moment that presents mostly in the evening/ nighttime everyday it wall worsened in January when I had a 4 hour long panic attack that set it all off, ive been diagnosed with GAD , Health anxiety, ocd in the past but right now my struggle is with panic attacks and derealisation. I’m seeing a therapist and I’m nearly done with a cbt course, I’ve improved a little on my own too by doing yoga and breathing exercises, but these changes are very slow and seem to help mostly with my daytime anxiety but the intense night anxiety is still there. 
I recently thought I would try going on citalopram again so that it gives me some help(was on it twice in the past with no side effects ) got put on 10mg and in 3 days I got the worst side effects I’ve ever experienced, my anxiety was unbearable and I couldn’t  get out of bed or eat, I also got racing heart and chest pain. Now I know I should be giving it more time to settle but I’m way too scared and I don’t think I can bare 2 weeks of this. I’ve talked to my doctor and she told me to stop it and prescribed mirtazapine. 
Anyways at this point i feel like I don’t have enough courage to try a new med  and I’m just so scared. I really want to try and treat myself without medication again but I feel lost as where to go from here.

(Ps : I’m 24 female )

So my question is : has anyone here managed to improve their severe-anxiety/panic without medication and how did you do it
