I’m sorry this has happened.
If you think you can keep him safe and yourselves also until you can get him to your Pdoc, I truly believe he needs a Pdoc’s Care now. As for stoping his meds ? I don’t think you have anything to worry about. But it does certainly appear his current meds just keep him to low/flat so that needs addressed anyway.
Allow your family to watch over him while you get sleep
Remember to keep your own selfcare on track.
You are on top of things and your son will feel better sooner
