Wondering if getting to know people is worth it

The more I try the more I'm finding I don't know if it's worth trying to connect with people. it takes a lot of emotional energy for me to connect with someone and for them to just abruptly decide to stop talking to me and not say hey this bothers me . No one seems to want to be honest and real anymore. Somehow I expect trolls/rude people to respond in a way to upset me so whatever.
