Hugs from me, too. I too am glad to hear that you've taken the step of talking with a professional on a regular basis, and gaining strength and insight from that.

Unless your sibling is mentally ill and you are his/her legal guardian (and it would appear that you aren't), you are not responsible for his/her behavior; (s)he is responsible for his/her own behavior. Don't ya go forgetting that between those twice-a-week sessions!

It's got to be more than tough to watch someone you grew up with hurting him/herself so badly. It's gotta hurt everyone else around him/her, too... even as far removed as the employer who had to make a hard decision in order to deal with his/her behavior. Just remember that your sibling got him/herself fired and will have gotten him/herself disowned, and (s)he is going to be the only one who can decide whether to get him/herself straightened out and stay straightened out.

Know that we are in your corner, even though you can't see us! :^)
