How to open up to people? How can I love anyone or myself when I know that people can be so cruel sometimes.?

their will always be cruel and evil people in this world,part of the healing process is letting yourself open up too someone who can understand you and has had the same experiences,you might have to talk to a few people before you find the right person you feel comfortable with. but never give up,from my experiences it took me a few years but I finally found peace and I do love myself now and have started to trust in people again.
