I don't think there's any drug that'll "Fix" your anxiety. The problem with benzos and anxiolytics is that they work short term but the tolerance is going to be bad and the rebound effect is going to be worse and last forever.
The right anti-depressant or ssri Might help, even if depression isn't the exact thing you're trying to resolve. As far as I understand, benzos or anxiolytics help manage the Really Bad Moments, the Peaks so to speak. But you cannot rely on them indefinitely.
SSRIs and antidepressants are kinda poorly understood. We generally know "okay this drugs tends to hekp helps" and "this drug does x to your brain" but not "this is how doing x to your brain maps to y behavior" (the latter is all theorizing based on empirical testing, but lacks the underlying explanatory rigor physics has).
Anyways, the most useful thing I've found both in my own life and in the experience of friends is: therapy. Often times therapy +some drug to help manage things, but I think therapy forms the basis of any mental health treatment. And it has to be a good therapist who Cares and knows you well (this latter point being something you can develop over time). I think the main battle with mental health is "changing how you think" and that's what therapy + medication is good for. Therapy helps reveal limiting beliefs, shines a light on the corners of your mind that you might be overlooking, and medication helps with implementing what you learn.
I'm not a doctor, and I'm not Your doctor, so grain of salt and all.
