Please tell me it gets better

Hi! I’m new here. I quit smoking dabs about one week ago and quit smoking flower about 4 days ago. I went to the ER on Sunday in a state of absolute panic and nausea. I have been heavily sweating, feel massive anxiety, nausea, and have lost about 11 pounds in one week. Please tell me this will end soon. I do not want to smoke again but these feelings are sometimes unbearable. I have two little boys (2&5) and all I want is to be able to take care of them and not feel like I’m going to die. I’m lucky to have a great support system so they are well taken care of regardless but I need some one to tell me there’s a light at the end of the tunnel because all I can see is black.
