Good crystals for stress relief: lepidolite, amazonite, amethyst, smoky quartz (can be used to ground stress), howlite, sodalite, blue lace agate, black tourmaline, selenite. I am sure I am forgetting some but those are some of my personal go-to stones for stress.

In addition to this, if you are sensitive to sound loop earplugs can be incredibly helpful in muffling a lot of excess sound. I use the engage earplugs when I want to hear conversation and such but block out some of the other loud environmental noises. They don't work for everyone but they can help.

Maybe Try Dravite ( Brown Tourmaline).. I Always Like That One... Rose Quartz, Moonstone..

I have neighbor problems too, but mine include my house being vandalized, and even voodoo work! All because I complained about the use of fireworks because I have anxiety issues and PTSD. I have been dealing with it for 4 years now, things are still the same, actually they have managed to get other neighbors against me. I have tried just about everything, and the police won't do anything. So, I know what you are going through and wish I could offer some advice that can help. What has helped me survive these past few years is just to keep telling myself that 1) the external is a projection of the internal, As Above, So Below, so any changes I have to make within myself instead of wasting energy fighting them because they are who they are and they won't change because they are totally convinced that they are right. And 2) That the Universe is responding to their vibration, so whatever they put out will come back, eventually. I just need to focus on myself and the changes I need to make to get a new vibration going which they won't be able to match, so the Universe has to remove them from my reality, sooner or later. It is not easy because they are so in my face and do whatever they can to trigger me, but I just gotta have faith. Any advice from the community would be appreciated.
