a lot of my anxieties and such have gone away after I became a Christian.
Jesus says,
"'Take My yoke upon you and learn from me, for I am gentle and lowly in heart, and you will find rest for your souls.'" (Matthew 11:29)
So, yes Jesus takes anxiety away. But we need to share with one another, and not try to hide in isolation in order to have peace. God makes us able to stay stable even while we are relating with various people who can be wrong and different than we are. So, it is good to seek God to have us doing well in this. This takes growing and correction and maturing.
So, it is good to be ready for love when going to a church >
"with all lowliness and gentleness, with longsuffering, bearing with one another in love," (Ephesians 4:2)
"Let all bitterness, wrath, anger, clamor, and evil speaking be put away from you, with all malice. And be kind to one another, tenderhearted, forgiving one another, even as God in Christ forgave you." (Ephesians 4:31-32)
So, I would say be ready for different people if you visit a church. Ones may be kind and sensitive and sensible and help you grow stronger in love. Others might be otherwise, and you, even a visitor, can be their example to help them find out how to love.
So, be ready for love, by sharing as family with any real Jesus people. And in case you discover a member or a pastor or another visitor is not for real, love that person by being his or her best friend . . . by being that person's example and not giving up on anyone
But I would not be too quick to trust anyone you don't know. One way to test, I think, is see who is feeding you very good example which helps you get more real with God, and they are every one's best friend by being a good example of how to love. These people can be in churches where even the pastor can have issues, but they have vision of hope like Jesus on the cross had hope for any and all people. So, these are the real pastors >
"nor as being lords over those entrusted to you, but being examples to the flock." (1 Peter 5:3)
It takes time to get to know someone so you know his or her example in real life. So, I would say be ready to spend time with people.
