Hello, I also was given a benzo, actually 2 they started me with lorazapam, and now I am on klonopin, I am 17 weeks post removal and had a HUGE mirena crash, still to this day I have bad days. I initially suffered from anxiety, nervousness, nausea, depression, panic attacks, and heart palpitations as well. I am getting better, my good days outweigh my bad ones but they are so frustrating, I am hoping my mirena blues will soon be over. I also am on 25mg of zoloft a day. Due to the benzo's being addictive. They want me to stabalize on the zoloft and them wean me off the benzo. Hopefully if all goes well I will be off of both by September. Good luck.
