anti-anxiety pills is a quite meaningless term, as it can encompass any of a number of drugs in different classes.
Valium (diazepam) is one anti-anxiety drug.
It's poor form to request a specific drug from a doctor, particularly one that is a controlled substance and prone to abuse. You will look like a druggie, and will almost certainly not get what you're asking for.
Instead, try giving a lucid picture of your symptoms and let the physician decide what is appropriate for you.
Anti anxiety pills give you some relaxation. So is the case with valium, but it has a little more effect. In acute anxiety stage, valium is being prescribed which has a little power to make you in more relaxed manner. If the dosage is more considering the fact that your resistance power is comparatively less, in normal circumstances, taking this medicine will have some adverse effect as well.
Valium (diazepam) is a benzodiazepine and as such is one of the drugs used to treat anxiety disorders. There are other classes of drugs also used to treat these disorders, as well. You can always ask, but your doctor may think another class of drug is more appropriate, or if he chooses a benzodiazepine he may think another in the lesson is a better selection. Asking specifically for Valium is likely to look something like a kid throwing a fit for mom to buy him a toy, considering how little you know about the treatment options, mechanisms of action, and adverse effect profiles. The physician is, after all, the expert here. That's why he's the one with the prescription pad.
I'm not a physician, but here goes: Valium is a benzodiazepine derivative. It enhances the effects of the neurotransmitter gamma-aminobutyric acid. This creates a sedative effect and, in turn, an anti-anxiety effect. Many contemporary anti-anxiety pills are ones which inhibit the reuptake of the neurotransmitters serotonin and norepinephrine which is likely caused by severe emotional stress. As a result, it is often regarded that more modern anti-anxiety pills target an underlying condition often instigated through emotional trauma.
