I take my meds at night, and I missed a dose on Monday. Tuesday I made it through, and I took my meds Tuesday, and Wednesday nights. Wednesday (yesterday) wasn't great, but I feel like shit today. 

Is it normal for withdrawal to take so long to set in? I'm depressed and anxious, but also my brain is messed up. I smell things that aren't there, everything is in slow motion, I have to work not to slur. Working today and staying on my feet for eight and a half hours was so hard. I want to self harm so bad right now and I don't know what's going on. 

Am I just having a weird depression episode, or is this withdrawal? Should I be concerned?
