Who can we trust?

In the times we're living is very hard to trust because the ones we trusted before did not do a good job when it was time to be grateful,on the contrary some people I helped with some shelter almost kicked me out of my place,and the bad thing about it is that it happened more than once with different people;I feel very sorry for the good people that have to pay for the actions of others but for me is almost impossible to trust anybody for the reasons I just explain,God bless the world and all of us from the evil that seems to dominate here on earth,because God is king of kings so there is nothing else that evil can touch or destroy God will teach it a lesson!
