I’m afraid that getting deeply involved in a church will cause you to build up even more resentment towards those you think are ruining your dreams of a happy life in San Diego.
From your other posts on immigration, Ireland and other matters it seems you are easily riled-up by what you perceive as wrongs. The truth is that there’s no right or wrong.
I think that if you want to find happiness and satisfaction you’d realize that no one is ruining your life. The world is fluid and ever changing. It up to you to adapt to it. If new immigrants can thrive in California, so can you. If you want a 3000sf house in a top school district in California, perhaps you should work a little harder or simply move out. Nobody is to blame for that.
