I'm suffering unwanted negative thoughts last 6 years which jems stones is best for me.God Bless you. Thanks.
I must say that it might be beneficial for you to speak with a doctor or counselor, since you've been having these negative thoughts for such a long time.
You might also find it beneficial to meditate with Rose Quartz, Black Tourmaline, and Lithium Quartz. If you don't wish to meditate, you could also simply carry them in your pocket.
I hope this helps!
