Hello Ilovehats, hi and welcome to the forums.
Firstly can I suggest you see another doctor, someone who cares for your well being and who can possibly help your child, if that's what he wants.
There is medication that will help stop certain addictions, but it will only work if that person wants it to, and if this possible then that's one problem you don't necessarily have to cope with, but at the moment trying to cope with all these issues could be keeping you physically sick, especially when you have COVID.
It's not easy dealing with everything you have mentioned because when any other small problem arises, it could multiple and eventually become another major concern, and with this, it could be the reason for your panic attacks, although I'm not a doctor to qualify this.
You have every right to decide you want to stop taking AD's, however, if they aren't working and your present doctor doesn't much care, then perhaps another doctor can help you further.
Struggling to cope with a child who has an addiction, makes you unsure of the direction you want to take, trying to protect your money, while still providing for them, but frightened of what may happen is always a great concern for you, and may cause much worry for you, and with all of this happening, then you need to ask your doctor for help.
I am really so sorry all of this is going on and want to help you as much as possible.
My very best.
