Hey Green Tea,
We have all been where you are at, feeling scared, lonely and like we have caused our world to cave in on us. One positive thing to hold onto, your boss obviously thinks highly of you or wouldn't have assisted with bail and stuff. Maybe say thank you and look to your boss as a possible source of support. Same for your co worker.
In terms of AA, it will not provide you an escape, there you will be asked to really take responsibility for what you have done and be accountable. That's the nature of the steps.
I know that my world fell in like yours and I even had passing thoughts of suicide. Don't give in to that depression, there is all sorts of help out there for it and you have so much to live for.
My thoughts are with you and good luck. Most importantly, welcome, thank you for sharing and being here.
Peace, Levi.
