Hi there ~
I understand your concerns. If you have eaten has brownies with weed and not feeling well, you need to go to the ER now. I believe that you might be having reactions to these drugs when you have taken them simultaneously. I also believe that the problem is also scary to have and you need to take it seriously enough to visit with a psychiatrist
who will help with your withdrawals. Please see a doctor as soon as possible.
I hope this helps. Take care and have a lovely day!
