Check out propranolol, gabapentin, and maybe go back and ask specifically about non addictive options. You deserve to not worry about taking anxiety meds.

Klonopin is a type of benzodiazepine which are a class of drugs that kinda make you out of it, a little high even, or can knock you out. They are ok if you take them a couple times a month and shouldn't be addictive but might not help you perform higher functions (text taking) and are better for social panic or generalized panic where you would otherwise be immobile with fear.

Propanol is a beta-blocker which is a class of drug used to treat high blood pressure. This is not addictive in any way, but will lose effectiveness if taken too frequently. I actually have lower blood pressure most of the time but this still works for me. When I panic I'll have disproportionate reaction from my body, and this calms all the unnecessary reaction. An example is, if someone startles me by walking quietly and then talking to me, I'll have a panic attack. I'm not anxious in the situation and nothing is scary, but I have a very immediate and extensive reaction regardless.

Gabapentin is an anticonvulsant which is a class of drug used to treat unnecessary excitement in the brain. I haven't used this but it's also a good non addictive option.

I've also found that I personally have a large capacity for energy, and anxiety was my body's way of releasing it. I've been able to decrease my anxiety proportional to the amount of cardio I do, up to about an hour and 15 minutes of moderate to intense cardio. Any more cardio and I don't notice a difference in my anxiety levels, any less and I do notice my anxiety more. I'll note that mild cardio doesn't work nearly as well. I usually aim for 400 kcal/hour minimum to get my desired results. Just be sure to have complex carbohydrates in your diet so you can get through the whole thing.
