You must be sick as a dog right now. I've dealt with suboxone and opiate withdrawal, which is brutal but manageable. However, I had a good doctor that helped me taper. And I was very motivated to stop.
I never got into uppers, I get horrifically depressed with the crash. I don't know how you would be able to detox at home, in addition to your BP diagnosis your are withdrawing from several different meds at the same time, which could trigger and episode.
You would be safe in the hospital.
Withdrawal is awful. You will feel the after affects from the suboxone for a while but it is doable.
I understand not wanting to go inpatient but you have too many medical and psychological issues to do it yourself. It's unsafe. I just don't want you to suffer more than you need to.
At this point, put the job stuff out of your mind because you need to concentrate on you. You can do this!
