Has gambling treated your anxiety or has it made it worse?
It's bizzare question to ask in the first place.

If you or anyone who is struggling with managing their anxiety then they should consult a doctor or therapist and find ways to manage the symptoms that is the effective way to deal with anxiety disorder and it can be fatal in certain cases so don't think that gambling or be ready to take bigger risk is a way of treating it, it can make it much worse.
I agree with that. If the anxiety already exists, then we should not add more fuel to it by gambling. It's not a cure. Gambling could make it worse, and someone who is having a hard time controlling their anxiety should not take any risk of trying gambling as a cure to the problem.
Those who have that problem should seek help, and it's better if they can get away from vices that would add more problems. They need company, they need to relax, and try to enjoy life. I don't think you can find that in gambling. It's mostly stressful unless you win in the first bet, which is very rare to happen.
