Coming off the meds

I decided about three weeks ago that I would be stopping all my psychiatric medication as it was costing a fortune and not helping at all. I feel like I gave it enough time and belief and it was the right time to stop it. I tapered off the medicine slowly as advised by the sleep therapist (I did not receive a response to my email to my psychiatrist).  Whilst lowering the daily dosage I was fine, I didn't feel any side effects at all.  I was meant to wean for another week but on Friday I ended up sleeping at a friends house and didn't have my medicine with me so on Saturday I figured since I didn't take it the night before I may as well stop.  Sunday was okay but Monday...oh wow! I had the worst mood swings ever, I was literally raging like a bull. I had tingling feelings going up and down my body every couple of minutes, light headedness, dizzy, nauseous. The list goes on. I got into my car on Monday evening and just burst into tears. I wished I could be dead, I cried for death to come. I was sleeping at a friends house half an hour away and bawled my eyes out the whole way there. The symptom of withdrawl have eased very slightly but at least the mood swings have subsided.  The physical withdrawl is very intense though and I hope it begins to improve soon.
