I was 15 I did something similar and that landed me in ICU for a couple days followed by a week in the hospital then a few weeks in a psych ward in a different state. It took my years to get over how awful it was and all the associated feelings with it. My family didn't hold a grudge against me or anything bad, they tried to be very helpful after the incident. Don't be too hard on yourself and be gentle with yourself. It takes time and this process shouldn't be rushed. Being open and honest with your pdoc and therapist is key in your recover. I wish you the best of luck and hope this event will not occur again. I'm surprised that they let you go home after the incident and not put you into the psych wing at the hospital for evaluation and such. If you feel the need to get more help, maybe going inpatient could be helpful if you find your feelings and thoughts are over whelming. As for the family situation I would try to be more involved with them and hope that they will be understanding, this incident has affected them too.
