What should I do? I've made a lot of bad choices recently and I don't think I can stop.
What bad choices did you make, and do you want to stop making them?
There are too many, I keep making bad decisions and not caring about the consequences.
You should be able to recognize that your choices have consequences that can be harmful, and you should stop if you know that they are bad decisions.  Remember that the consequences will affect you in the future, so it makes sense to do things differently today.
But maybe my decisions are fine. And the consequences won't be so bad.
You have acknowledged that some choice that you've been making are bad. Now it's important for you to actively stop making those bad choices. By stopping now, you will set yourself up for a more fulfilling life.
