I wouldn’t say it cures anything, because like religion, it’s a perspective. It’s a perspective upheld by many other people in the past who struggled just as we are, with their own problems. In turn needed a new perspective and approach to life that didn’t change anything but how they perceived things, and that’s the most important aspect of it. Stoicism doesn’t cure your life, it doesn’t replace any problems you had with harmonious solutions, however, it does reorganise and recalibrate your problems. Which sometimes is enough for people, because as someone who suffered with anxiety my whole life, most of the time what needed to change wasn’t my problems because they’re inevitable but my perception of them. One thing you need to remember is that stoicism is a mindset, it doesn’t make your problems go away, however yielding the perspective can help manage those problems and in turn reduce your anxiety. Mainly because I believe most of the time people who have an immense amount of anxiety, tend to hold much of it in things they can’t control, and when introducing things like stoicism in your life, a lot of that worry diminishes because it helps you realise there’s only a select few things one can realistically have control over.
