Also you cant rely on benzos to seriously tackle your anxiety, IME, they only make it worse in the sense you become somewhat mentally dependant, just not to having the benzo in your blood but dependant on having them at arms reach to feel comfortable and anxiety and thats just a stupid way to treat anxiety.
Unless you have PTSD and it was hardcore trauma and you're in the fetal position in bed all day scared to leave your house then benzos are the better alternative. But they wont improve your anxiety, they will mask it and only compound the original problem, as you're just teaching your brain to unlearn any old coping mechanisms you had and to just rely on the benzo to cope with anxiety.
Cognitive Behavioral Therapy or whatever it is called is a much better option, you will actually improve your brain and bodies reaction to perceived fears, as opposed to just masking them, and thinking everything is okay.
Inevitably your tolerance will rise, the benzo dose will either need to be increased, compounding the problem of addiction(the very same problem you seem to be scared of when it comes to the 'done).
So sorry to preach man, but benzos dont have any place in treating anxiety disorders, they only make your problem worse. Exposure therapy is best, and "flooding" a technique of flooding the sufferer with sources of anxiety and making the patient wait with the anxiety experience it, then try to rationanalize it ect.
Doing this daily will unlearn the learned reactions you'ved developed in life to the point where you feel as though you NEED benzos just to function in society. I'm in no way putting you down for feeling this way, as i was the same, and i of course at the start would have rather stayed on benzos to control this shitty condition, but over time you start to work out that the benzos only truely work for small amounts of time until your dose must be increased ect.
Choice 1: Take benzos and avoid your problem, let it compound, and just keep running from the original problem.
Choice 2: Stop taking benzos and actually start attacking these flaws in your thinking.
Goodluck man, the thing is the benzos take the effort of just taking a drug, literally curing your problem(keep in mind everyone feels anxiety, you cannot expect to never be nervous) is going to take sustained effort daily for weeks to months.. But the end outcome is much better than benzo dependancy.
