You cannot change others, you can only change how you react. But thats already a lot. Mindfulness and self-reflection are great tools! Great job!

Also I think, there are so many people worth trusting them!

So many do not of course. But anyway, how many you need? You cannot keep a good relation with really ALL people. So it does not even matter at the end if not all people are like that.

Wish you a great and relaxed day! 💜
