No, stimulants allow me to think faster. A lot of my anxiety is because I feel like I can't think fast enough to keep up with the world around me. Especially things like driving. Now I'm taking a Chinese medicine and cutting my caffeine intake down, but before I just ran on caffeine. Caffeine and stimulants tend to get me more talkative and outgoing, too. Ritalin however didn't work for me, though. Maybe amphetamines would be better, but longterm stimulant use isn't good as it shoots your adrenal glands to hell.
So my Chinese medicine is hawthorn berries and eucommia bark and a little Astragalus made into a tea. Traditional Chinese Medicine has eucommia bark being good for replenishing kidney jing (basically adrenal hormones) and Western science shows Eucommia Bark is a SARM, selective androgen receptor modulator, basically somewhat like a steroid without the side effects. The hawthorn berries are good for the heart, and in Chinese medicine it's quite interesting, as it's like old love songs and whatnot, where the heart is the center of emotions and whatnot. So, it has really good like, anti-anxiety and anti-depressive effects for me. Astragalus is a ki-booster, and it's also good to throw into a formula to harmonize the other herbs. I use raw herbs and make tea. Some people might say this sorta thing is hokey, but, if it works, it works, and it seems to be working better. I've had much better luck with herbal medicine than pharmaceutical drugs. For example, Rhodiola Rosea is a stimulant/SNRI, and I felt WAY better on that stuff than on Ritalin. Light years better. So take all that for what you want.
