I don't doubt for one minute that they mostly have genuine issues, but it's almost like that is who they are and don't really want to be any different. They enjoy the sympathy until it all starts to become clear that they aren't getting the desired attention any more. Then they'll blame that person and fall out with them.
I used to let myself be drawn in until I got drained but I don't any longer. I tell it like it is and if they don't like it I let them walk away and criticise me because I know my church friends would tell them the same things.
People are weak in certain areas, some in the faith, some are stuck in a pit of desponcy, some have no self control at all and no discipline. They can't seem to help themselves get out of this rut so expect others to be there to lean on or take from.
We are told to come alongside the weak in faith and encourage them.
But advice needs to be put into action, they need to be responsible for their lives. If a person is not willing to do what is necessary, take baby steps forward by solving problems one at a time instead of avoiding them, make a plan, set goals and do the work, you can't help them. This is usually yhe case with people who dony ha e the Lord, but sometimes new believers are still struggling with dying to their old self and walking in the spirt, instead of in the flesh. You pray for them, with them and leave the rest to God.
I have a leach in my family that just expects every one to keep giving to her. She drained her husband for 15 years, taking and not loving, had four kids and decided to leave all of them to seek a millionare boyfriend, then when that didn't work, a million dollar Marijuana business. Having nothing to start with, she would con others to invest with promises of tripling their money in no time. Fools ventured into it and lost lots. We warned her way before she left her husband to stay with Him, love her kids and him to the bedt of her ability. Well that wasn't any fun.
Her older teenage doesn't want anything to do with her - he is tired of being drained and treated like her butler. Her own kids will be her judge in life. I always said If you can't be a responsible parent and love them, it really doesn't matter what else you do in life - you are a failure. But of course, even so, Jesus saves failures.
She tried to move in with us, she exclaimed, "Just for a couple weeks until I can find a place!" With terrible credit, numerous evictions after draining the blood out of all those who had mercy and gave her a chance, with no job or willingness to get one and work from the bottom up, I said NO! That would have taken my grace away. In others words, she is a disgrace! This is my sanctuary and allowing responsible selfish people to destroy it is not an option.
So, help in the beginning, yes, but you have to draw the line. God draws the line, He says if you don't work, you don't eat! We must be responsible for our lives.
There is another spiritual principle in the works here: What you sow is what you reap! People are living miserably because they created it themselves. They are reaping what they have sown. They are usually selfish, even narcistic. If you focus on yourself too much, you have no time to give to others and so you reap nothing in life.
There are two pieces of advice depending on the person in need.
1. A famous psychoanalyst was asked the question: "If you were so depressed, even to the point of commiting suicide, what would you do"?
He responded, "I would go out and find someine to help, after that, I would search for more and help more." Why would you do that? You take the focus off yourself, you stop being selfish, start loving others and you are healed in the process.
2. Memorize the Sermon on the Mount. By the time you have it accomplished, you'll have forgotten what you were depressed about.
