You told op to go to therapy....
...and? Is therapy, or thinking that someone might possibly benefit from it, sinful now?
To be precise, though, I did not NOT tell you to go to therapy, I deliberately said this:
Some time back it was recommended that you seek professional help. I can't say that that advice was wrong. Hard as it may be to admit, your biggest problems might be yours, and not due to everyone and everything outside yourself.
If I were Croix, I would say that you need your ass kicked. And there's truth to that, I'm sure that it would be of some help. But it would likely only result in an external change. As long as someone is around, you'd act better, but as soon as the pressure was off it'd be back to the same silliness.
I'm convinced that there is an aspect of maturing that is of free choice. One has to consciously decide to grow up, to be willing to do the necessary work. But you have to do it ONLY because you want to. You shouldn't do it for me or for anyone else here, or for your family, or (you'll probably consider it highly impious of me to say) even for God Himself. You should do it for YOU.
So, as far as therapy goes, I have not and would not absolutely tell you to go. Anyways, unless you want it, want to see if it's a tool that might be helpful, and are willing to put in the work, it wouldn't do any good.
An additional point about external factors that I think deserving of consideration. Immaturity, or delayed maturity, is becoming a more and more common problem in the world, especially the West.
1) Technology and social programs have taken much of the physical danger out of life. The effects of an action, or inaction, are no longer so immediate. So people don't learn simple lessons and skills that should be, and were once considered, common sense.
2) Lack of fathers in the home. People do sometimes need a kick in the butt. Dad is usually the one best equipped to give it.
I give these as reasons to help explain a phenomenon, NOT to be used to further a shitty, excuse seeking, paralyzing attitude. When you have a need that isn't being met, obey our Lord's directive, "Seek and you shall find".
Technology causing you problems? Shut it off or at least figure out a way to use it as a help rather than a hindrance to your advancement.
No dad around to kick you in the butt? Then you better learn to kick it yourself.
You fail, fall back into old habits? Get up, try to figure out what went wrong, make changes and try again. And again. And again. And again...... as many times as necessary.
You want to dismiss this as a bunch out of touch boomer platitudes? Go right ahead. No one owes you guys a damn thing and I'm guilt-trip proof. When you get old enough, you'll realize that the only person you've really been hurting with your crap is yourself, and it's your own fault.

Now I'm off to do fun boomer things. See Ya!
