Supplements that help panic disorder/agoraphobia?

I have Panic Disorder, Agoraphobia, PTSD, OCD, Depression, DPDR, the list goes on and on… REALLY curious to hear about 5-HTP?? Has it worked for anyone?? Anyone side effects?? I’m REALLY scared of meds and supplements due to a very severe reaction… also wondering if anyone here has tried Passion Flower?? Read a study that passion flower can work like a benzo. Anything helps! Thank you!!
