What medications have most been helpful to you?

Hi I’ll keep it short and sweet, been looking for some medications to help with panic disorder. Been struggling with panic attacks for about 6 months and it has caused me a massive descent in both life and work. Have worked as a firefighter for a few years and this is obviously a big problem in that environment. Also in life anything feeling confined is rough so like traffic, large buildings far from exits stuff like that. I have some clues to what may have sparked this but either way I’m here now. Any pointers would be great! Also probably will look into this with my doctor asap. I so far have lowered caffeine a bunch and take L-theanine which is pretty good stuff
