Personally, my obligation to a friend or anybody else for that matter ends the moment that person's actions become a threat to my own life or well being.

Call me heartless, but if another person is making foolish decisions and those decisions put either my life or my mental or physical health at risk, I'm not dealing with them. If a person is consistently putting me at risk, then they are getting kicked out my my life for good.

Don't get me wrong, I'm not saying that I wouldn't help a loved one who is in actual legitimate danger that they didn't choose to get in, however, if somebody is making foolish decisions that affect me negatively that they can choose not to do, yet they won't make an effort to change and/or get help, then they are not worthy of being in my life.

I know I sound cold and heartless but it takes a great deal of energy just to function in society with all of my mental health issues. Going to school, working, and keeping myself from getting overwhelmed and making foolish decisions that endanger other people myself take a significant amount of time and energy. After all is said and done, I have very limited energy to deal with people, therefore, I choose who I allow in my life very carefully.
