loud kids' noise

I've been depressed for years due to my disease (psoriatic arthritis) and what is making me worse is all the noise I have to deal with that young kids in my complex -now it's May they are out making as much noise as they please until 8pm (or later) and it is stressing me out! a nice playground but they'd rather make noise running or riding bikes, even screaming just when they are making a huge mess with sidewalk chalk, just because they feel like it! Parents' don't say a thing and I've told them many times it bothers me and I can hear them with windows/doors closed. I don't know how to get through this summer (had to put up with this for the past 4 years). I can't move due to how I feel and the cost of housing in my area and worry some place may be even worse than it is here! Days aren't bad, fall/winter is great as most are inside esp. when it rains but this witch across the road thinks she can let her brats do whatever they please, help!
