SS - Try some deep, slow breathing for a minute or two. It helps calm that hyped-up feeling.
Are you going into rehab tomorrow? I know it's difficult to deal with all your emotions right now, but you only have a matter of hours until you can focus on recovery and not have all these distractions. You'll be able to talk about ALL of it once you get to treatment. So hang tough, OK?
I know how hard it is to live with your parents right now, but they're probably having a rough time, too. It's confusing because you want to be treated like an adult and have certain freedoms, but you're still a dependent child in many ways. Add alcoholism into the picture, and what's a parent to do? Look at this as a transition time on the way to better days.....and try to let things go as much as possible. Remember also, that alot of your extreme emotions are part and parcel of the first days of recovery. So, it's normal, and it really will get better....... sending hugs.....
