Why does bad things happen to good people.

Im not perfect but I’ve been a good person to everyone I know, I put their needs over mine. Recently I’ve hit my rock bottom, one after another, then another. I really don’t know what to do anymore. I was the one hurting yet I’m being disregarded by people. I was the one having being wronged but Im just pathetic because I keep my mouth shut by the bad things they did to me. Ik the one crying every night and the people that got away is happy and celebrating. I don’t know what to do😭. Everything hurts, everything is just getting worse and worse everyday😭.
