Your friend is in crisis...and so are you bpdruins.

The majority of the responders are veterans and will do everything they can to help you and support your friend.

Jmo, your loyalty to your friend is commendable, but you are jeopardizing your freedom and possibly your life.
Reaching out for help and advice here is a good first step. The anonymity feels safe and allows for honesty, and it can be a release of fear and frustration.
Perhaps you are beginning to understand that you have no control over his actions, but you do your own.
Whenever we take care of ourselves it can unleash feelings of guilt and sometimes shame...and that can become a trap, one that is hard to get out of.

It is not giving up on your friend for you to take care of you...doing it is healthy but hard to do, loving yet it feels lonely, and it may feel like you are being selfish when the reality is you need to protect yourself.
