Get a dog. If you feed him, play with him and treat him well, he'll love you from the bottom of his cuddly dog heart. A dog loving his human is probably the purest form of love there is.
With regards to other humans, selfishness and ego comes into play. So you aren't wrong in your distrust. I heavily distrust others, including my parents. But I think the idea is to have faith in the goodness of others. If you have no faith or hope, you'll just be bitter and lost.
Have faith in humanity and have faith in yourself. Do healthy activities that you like that involve meeting other people. You can also try volunteering for a cause you care about and maybe you'll see there is good to people even if the majority of us are deeply, irrevocably flawed.
Hope you have a good day and a peaceful weekend
